JATZEK MusicMaster Periodical 10

Composing, Arranging and Orchestrating Music

Philip John Jatzek & STORM (ChatGPT) | Working draft | 25 September 2026

This volume turns D melodic minor note choices into playable parts for a group. The catalog lists every distinct selection of two through seven pitch classes, while the arranging examples show how a bass, guitar, keyboard and melody instrument can share them. A note set identifies the available pitches; octave, bass note, spacing and rhythm determine how it actually sounds.

1 Scope and naming rules

Use ascending D melodic minor: D E F G A B C# D. This is the concert pitch reference for the catalog. In classical descending melodic minor, the line usually returns as D C Bb A G F E D; that descending collection requires a separate catalog. Do not mix Bb and C into the present ascending list without marking a scale change.

D is the performance root of the scale, but it is not automatically the root of every chord. A two-note set is named as an interval. A three- or four-note set receives a chord name only when its pitch classes match one of the seven diatonic tertian stacks listed below. All other sets retain a precise note-set identity until the player chooses a bass and voicing. This avoids assigning a misleading unique chord name to a set that admits several interpretations.

D-G-C-F-A-D guitar tuning is read from lowest sounding String 6 D to highest String 1 D in the fretboard convention used here. Score examples state sounding concert pitch explicitly; write a separate transposed part when an instrument requires one.

2 Diatonic chord anchors

Degree	Triad notes and name	Seventh notes and name
1	D F A — D minor	D F A C# — D minor major seventh
2	E G B — E minor	E G B D — E minor seventh
3	F A C# — F augmented	F A C# E — F augmented major seventh
4	G B D — G major	G B D F — G dominant seventh
5	A C# E — A major	A C# E G — A dominant seventh
6	B D F — B diminished	B D F A — B half diminished seventh
7	C# E G — C# diminished	C# E G B — C# half diminished seventh

For example, D–F–A–C# is D minor major seventh even though the scale has D as its tonal centre. E–G–B–D is E minor seventh. Changing the lowest sounding note can produce an inversion or a different hearing of the same pitch classes.

3 Orchestration and notation workflow

Choose a sounding register: Write each pitch with an octave number, such as D3 for bass and C#5 for melody. A pitch-class catalog alone cannot show spacing or instrument range.

Write one concert score: Put the pulse, barlines, time signature and rehearsal marks in one master score. Identify any octave-transposing or key-transposing parts before preparing players’ pages.

Assign a function: Give bass the foundation, rhythm guitar a compact attack, keyboard a contrasting register, and lead instrument a phrase. These are choices for one arrangement, not compulsory assignments.

Check the vertical event: At each attack, read all simultaneously sounding notes, including held notes. Compare the result with the chosen catalog row, then listen for crowding, tension and unintended clashes.

Check the horizontal line: A sequence can move outside one vertical sonority while remaining in D melodic minor. Mark every altered or borrowed pitch when it appears.

4 Four bar concert pitch sketch

Example in 4/4, quarter note = 80. Each cell describes the sounding pitches and their entrance; hold a pitch only where stated. This is an arranging map for later staff notation, not a finished orchestral score.

Part	Bar 1 Dm	Bar 2 G	Bar 3 A7	Bar 4 Dm maj7
Bass	D2 on 1 and 3	G2 on 1 and 3	A2 on 1 and 3	D2 whole note
Guitar	D3 F3 A3 short on 2 and 4	G3 B3 D4 short on 2 and 4	A3 C#4 E4 G4 on 2 and 4	D3 A3 on 2; F3 C#4 on 4
Keyboard	F4 A4 on beat 1	B4 D5 on beat 1	C#5 E5 G5 on beat 1	F4 A4 C#5 on beat 1
Lead	A4 quarter then G4 quarter	B4 half then A4 half	G4 E4 C#5 A4 quarters	C#5 to D5 half notes

Check: Bar 1 combines D F A G, so its passing G is a scale tone outside the D minor triad. Bar 2 combines G B D A. Bar 3 combines A C# E G. Bar 4 combines D F A C# plus the final melodic D. The catalog below is for identifying simultaneous subsets, not for claiming every bar contains only one chord.

5 Complete pitch collection catalog

There are 21 dyads, 35 triads, 35 four-note sets, 21 five-note sets, 7 six-note sets and 1 seven-note set: 120 selections total. IDs are stable catalog references. Notes are in scale order; they do not prescribe bass, octave, or playing order. Semitones show pitch-class distance above D (0 2 3 5 7 9 11).

6 How to use the catalog in rehearsal

Choose a row and give each listed pitch to one or more instruments. Doubling a pitch in another octave does not add a new pitch class. Play with the bass on D first; then change the bass and compare the perceived chord root. For two notes, alternate simultaneous attacks with question-and-answer phrases. For five to seven notes, spread tones across octaves and stagger entrances before trying a dense simultaneous attack.

Suggested first experiment: 2-04 D A as bass and guitar; 3-07 D F A as bass, guitar and keyboard; then 4-15 D F A C# with C# in the lead. Compare the sound, then change only the top voice.

ARRANGEMENT HANDOFF ONE OF THESE DAYS

Use the eight-bar song passage in Periodical 9 as an arrangement exercise. Its concert chord sequence is D–Bb–C–D, twice; the E–C–D–E labels are guitar shapes for the D–G–C–F–A–D tuning. Put concert chords above the full score and retain the shape labels only on the guitar part.

Mark the bar-4 drum fill as the first boundary and the bar-8 fill as the exit. Keep the written bass change from eighth notes in bars 1–4 to quarter notes in bars 5–8; listen for the resulting change in energy before adding another layer. Check whether the guitar detail in the second half overlaps a lyric or another instrument.

Deliver a compact handoff table with bar, concert chord, guitar shape, bass rhythm, drum cue, vocal space and instrument entrance. Compare it against the Periodical 9 score before the DAW session described in Periodical 11.

FURTHER DOCUMENTATION | Score and part checks for the D melodic minor catalogue

Research addition • 26 September 2026 • Philip John Jatzek & STORM (ChatGPT)

The 120 catalogue rows enumerate pitch-class subsets of seven notes, not 120 unique named chords. To turn a selected row into a sounding arrangement, specify the octave of each pitch, its performer, the beat of its entrance, and its duration. Then inspect the simultaneous notes at every attack and every sustained overlap.

Keep a concert-pitch master score for comparison. If an instrument transposes, prepare a correctly transposed player part from the same sounding pitches. Rehearsal marks, bar numbers, rests, and clear rhythm in each part let the musicians test the four-bar sketch rather than infer timing from the note list.

NEED TO KNOW | PERIODICAL 10

Writing for real players and instruments

Assign a function to every part

Label each line melody, counterline, harmony, bass, pulse, or texture. Two lines in the same register and rhythm can mask each other unless their doubling is intentional.

Check range and comfort

Compare every written line with the intended instrument’s playable range and comfortable register. Try a practical tempo before deciding that a notated figure is performable.

Build texture in stages

Begin with melody and bass, add essential harmony, then optional color or rhythmic doubles. Listen after every layer to see whether the main line remains audible.

Prepare a readable rehearsal version

State tempo, meter, repeats, articulations, dynamics, entrances, and ending. Give performers enough information to reproduce the intended arrangement.

7 Practical algorithms for composing arranging and band orchestration

Use these procedures with the 120 pitch collections in Section 5. A catalogue row supplies possible pitch classes; an actual piece also needs a tonic or bass context, octave, duration, rhythm, articulation and an instrument that can play each line. These are decision procedures for writing and rehearsal, not automatic judgments of musical quality.

7.1 Shared song map

Algorithm 1 Define the brief and source material

Input: A song idea, available players, intended audience and time limit.

1. Write one sentence for the musical or lyrical point of the piece and list the available singers and instruments.

2. Set an approximate tempo, meter, form and target duration; identify where the main melody belongs.

3. Make a lead sheet with melody, chord symbols, lyric cues and bar numbers. Mark any idea still undecided.

Pass test: A player can describe the form and sing or play the main idea from the lead sheet.

Watch for: A polished sound concealing an unfinished melody; a part written for a player or instrument you do not have.

Algorithm 2 Maintain the pitch and event ledger

Input: A scale choice, chord plan and a concert-pitch master score.

1. State the sounding scale and its direction or altered tones. For this chapter the ascending collection is D E F G A B C#; classical descending melodic minor may use C and Bb.

2. At each chord change, write its root, chord tones and bass note. List sounding pitches held over the barline as well as new attacks.

3. Flag pitches outside the chosen collection as chromatic, borrowed or intentionally conflicting. Resolve ambiguities by listening and by labeling the part.

Pass test: Every simultaneous event can be reconstructed as pitches with octaves, even if a catalogue row contains fewer pitch classes.

Watch for: Treating an allowed scale tone as automatically consonant above every bass; overlooking a held note when the chord changes.

D melodic minor example: Over D minor-major seventh, D–F–A–C# are chord tones; G can be used as an intentional melodic neighbor rather than presumed part of the chord.

7.2 Composition algorithms

Algorithm 3 Generate and select a motif

Input: A sung phrase, guitar figure, rhythmic cell or short pitch contour.

1. Record three two-bar ideas at the same tempo; keep their rhythm and contour audible without effects.

2. Choose the idea that is easiest to recognize after one hearing. Write its exact rhythm and pitches.

3. Answer it in the next two bars by repeating, sequencing, reversing contour, or changing only its ending.

Pass test: The response is related to the opening but has a destination.

Watch for: Introducing a new unrelated figure each bar; assuming more notes make a stronger hook.

D melodic minor example: Try D–F–E–D as a motif, then retain its rhythm while answering A–C#–B–A.

Algorithm 4 Set melody against harmony

Input: A motif, a provisional bass and one or more chord choices per phrase.

1. Place structurally important melody notes on the strong beats; test how each sits above the current bass and chord.

2. Choose when each chord changes, not only its name. Delay or advance a change to support the melody’s point of arrival.

3. Use passing or neighboring notes between clear targets; sing across the change and revise awkward leaps or stresses.

Pass test: The melody communicates even with one quiet chord instrument; dissonances have an intended duration and exit.

Watch for: A chord symbol that contradicts the audible bass; assuming a chord name validates every melody note.

D melodic minor example: In Dm(maj7) → G7 → A7 → Dm(maj7), try melody targets F → B → C# → D and listen to how each target leads forward.

Algorithm 5 Build phrase and section form

Input: A complete motif and a few four-bar phrases.

1. Give each section one role, such as establish, intensify, contrast or return. Sketch bar counts and lyric or instrumental entries.

2. Make the second phrase answer the first. Vary one or two factors: ending pitch, register, rhythm, harmony or phrase length.

3. Play the whole form with only voice and one accompanying instrument; shorten any passage whose purpose is already clear.

Pass test: A listener can distinguish the sections and anticipate the return of the main idea.

Watch for: A repeated section that changes neither story nor musical energy; adding a bridge merely to fill time.

Algorithm 6 Write a second independent line

Input: A completed lead melody with known rests and chord changes.

1. Find a gap in the lead line and draft a short answer, countermelody or bass response.

2. Check every vertical meeting with the lead and harmony, including notes sustained from earlier beats.

3. Keep the secondary line lower in priority through register, rhythm, length or dynamics; remove it under dense lead phrases.

Pass test: The lead remains recognizable when both lines play; the added line still sounds like a line by itself.

Watch for: Two melodies in the same register with nonstop notes; a counterline that only duplicates the lead by accident.

7.3 Arrangement algorithms

Algorithm 7 Design an energy map

Input: A finished lead sheet and target song form.

1. For each section, mark intensity from 1 to 5 and name the leading element: voice, guitar riff, drums or another part.

2. Plan entrances, exits, register rises, rests and dynamic changes that create the desired contour.

3. Compare adjacent sections by listening. Change at least one audible element at a transition that needs emphasis.

Pass test: The chorus, bridge and ending have distinct shapes without masking the song.

Watch for: All players at maximum density from the first bar; every chorus identical without a reason.

Algorithm 8 Build a rhythm-section groove

Input: A tempo, meter, chord rhythm and stylistic reference.

1. Write the main drum pulse and accents; decide whether bass follows kick attacks, sustains across them or answers between them.

2. Add the guitar or keyboard comping rhythm and mark where each player rests. Test with drums and bass alone, then add harmony.

3. Compare subdivisions and check that the parts agree on stops, pushes, pickups and section changes.

Pass test: The groove is intelligible with drums and bass and leaves room for the lead.

Watch for: Kick and bass accents that unintentionally disagree; competing busy rhythms from guitar and keys.

Algorithm 9 Allocate attention and space

Input: A band lineup, lead melody and energy map.

1. Assign a primary, supporting or silent role to each instrument in each section.

2. When parts collide, change entrance time first, then rhythm, register, voicing, articulation or level; compare versions.

3. Keep deliberate doubling if it strengthens a hook, and label the octave and unison explicitly.

Pass test: A listener can identify the lead and the accompaniment’s job at every section.

Watch for: Writing sustained full chords for guitar and keys in the same octave during a vocal; filling every rest.

Algorithm 10 Shape transitions and ending

Input: A playable verse, chorus and other sections.

1. Choose a count-in or pickup and one clear cue into the first phrase.

2. At each boundary write the last beat, fill or stop, and the first beat of the next section; rehearse the two-bar join.

3. Specify whether the ending rings, fades in production, repeats with a cue, or cuts off together.

Pass test: Players agree on bar counts and can perform every boundary without a spoken reminder.

Watch for: A fill that obscures the singer’s pickup; an ending that exists only as an unspecified DAW fade.

7.4 Orchestration and band-part algorithms

Algorithm 11 Assign sounding roles and registers

Input: A finished arrangement and the actual players.

1. Write a concert-pitch map with each instrument’s main function, approximate register and desired tone color.

2. Put bass and low rhythmic information below the principal harmony; choose a lead register and keep competing parts away unless they intentionally double.

3. Test the section at performance volume; thin or move voicings that conceal a featured line.

Pass test: Each player knows what their part contributes, and the main line remains audible.

Watch for: Assuming different instruments cannot mask each other; assigning every chord tone to every player.

D melodic minor example: For Dm(maj7), let bass sound D2, guitar F3–A3, keys C#4 and lead D5; these octaves are a test setup, not required voicing.

Algorithm 12 Check playable writing

Input: A draft line, specified instrument, tuning and expected performer.

1. Check range, hand span, string or fret positions, breath or vocal limits where relevant, and whether notes can be held while the next gesture occurs.

2. Mark picking or strumming pattern, sustain, muting, bends, slides and instrument changes when essential.

3. Ask a player to try the hardest two bars at tempo; simplify or redistribute any unreliable passage.

Pass test: The performer can repeat the part cleanly at tempo without hiding notes or changing the written rhythm.

Watch for: Mistaking a MIDI playback for a live performance test; writing guitar chords that require impossible simultaneous frets.

Algorithm 13 Voice-lead and double intentionally

Input: A chord sequence and candidate instrumental voicings.

1. Keep shared chord tones where useful and move changing voices to nearby targets; trace each line horizontally.

2. Decide which tone belongs in the bass and which, if any, should be doubled in another octave.

3. Compare the version with and without each doubled tone; retain the double when it clarifies color, melody or impact.

Pass test: Each part has a singable path and the vertical chords express the intended harmony.

Watch for: Parallel parts that obscure the melody; doubling a dissonant note accidentally.

D melodic minor example: From D–F–A–C# to G–B–D–F, F can remain while C# moves to D and A moves to B, subject to chosen register.

Algorithm 14 Produce score and player parts

Input: A validated concert-pitch score and confirmed instrument list.

1. Write tempo, meter, key or scale note, barlines, rehearsal letters, repeats, dynamics, articulations and clear entrances in the master.

2. Generate each readable part from the same score. Apply any instrument transposition and standard octave convention; label guitar tuning D–G–C–F–A–D when used.

3. Check rests, page turns, pickups and cues against the master; have players identify a rehearsal location by bar and letter.

Pass test: Every player can start at the same marked bar and produce the intended sounding pitches.

Watch for: Mixing concert and transposed pitches without labels; using a pitch-class set as if it were a finished part.

Algorithm 15 Rehearse, record and revise

Input: A band-ready score and a rough rehearsal recording.

1. Rehearse the rhythm section, add melody and harmony, then add secondary lines and effects one at a time.

2. Listen once for form, once for timing, once for intelligibility and once for pitch conflicts. Write each issue with bar number and proposed fix.

3. Change one cause, run the passage again and record whether it improved; update the master and player parts together.

Pass test: The group can repeat the arrangement reliably and the revision is present in every affected part.

Watch for: Fixing a writing problem only by raising the volume; correcting a part verbally but leaving the score outdated.

7.5 One complete four-bar application

Concert pitch, 4/4. Start with a spare D melodic minor phrase. These are sample choices for testing the procedure, not the only valid use of the collection.

Bar 1 Dm(maj7): bass D2 on beat 1; guitar F3–A3 in two short attacks; keyboard C#4 held softly; lead enters F4–E4–D4.

Bar 2 G7: bass G2; guitar B3–F4 briefly; keyboard rests; lead targets B4 after the guitar attack.

Bar 3 A7: bass A2; drums make a short fill after beat 3; guitar C#4–G4; lead C#5 held into beat 4.

Bar 4 Dm(maj7): bass D2; guitar D4–F4–A4 with a single final attack; lead resolves to D5; all parts cut off together on the agreed beat.

Check the actual sounding register and every overlap. If the held C# from bar 1 enters the G7 bar, either release it at the barline or treat it as an intentional tension. Rehearse bars 3–4 separately so the fill cannot hide the final entrance.

7.6 Working checklist

Composition Is the motif recognizable, the melody singable, the harmonic rhythm purposeful and each section necessary?

Arrangement Is the lead clear, the groove coherent, the energy map audible and each transition rehearsable?

Band orchestration Are the pitches, octaves, tuning, rests, ranges, articulations and cues playable and unambiguous?

Rehearsal Did a recording reveal masking, timing disagreement, pitch clashes or missing information in a player part?
