The idea
A motive is small enough to be incomplete, and that is the whole point of it. A melody is a finished statement and resists development, because to develop it you first have to break it into pieces. A motive is already a piece, so it goes to work immediately. Greg puts the floor low: a motif "could be as simple as two notes, it could be an interval."
The rule that tells you development is actually happening is written down in the Somewhere master class. Bar 1 states an idea. Bar 2 varies it, removing a note or altering the rhythm. Bar 3 and everything after must relate to what you set up, building tension as a question or resolving as an answer. "If Bar 3 doesn't relate to Bars 1 and 2, you're not saying anything. You're just playing notes."
What changes is what you do after you play something good. Right now the good idea arrives and then a different idea arrives. By the end of this lesson the second idea is the first idea, altered on purpose.

Motivic Development??? (https://www.youtube.com/watch?v=M50BjzMm67w)
- Define a cell of exactly three notes. Greg's is a half step plus a whole step [00:33].
- Go through a whole tune playing only that cell, out of time, "so you can actually explore" [00:44].
- The order of operations on each chord: look at the chord, decide where the cell should land, land "ideally on a chord tone" rather than an upper extension, then work backwards to find the approach [00:59].
- Reorder and flip the cell freely, in any arrangement of the notes, up or down, as long as you land on the chord tone you chose [01:44]. The payoffs: foresight about where you land, and consistent material to get there [02:47]. Become more Musical in your Piano Solos (https://www.youtube.com/watch?v=a1rtPDUSBhQ)
- Keep the whole solo inside one octave, 5 to 5. He plays the unrestricted version first as a control and asks "it's not very musical, is it?" [00:35]. Once the octave is fluent, add patterns inside the key [02:35].
- The test for a pattern: a beginning and a deliberate close, "like tie a little knot on it" [02:51].
- The dose: fifteen minutes a day for a month, moving the octave up chromatically through all twelve keys [03:45], [05:04]. How to improvise with musicality (https://www.youtube.com/watch?v=uwbz6eOGm1k)
- "The things that make music sound good don't have anything to do with how complex it is" [01:46].
- One note creates an expectation, and everything after it is heard in relation to that note [02:08]. Interval distance is content: a note, a note a major 7th away, then a note close by [02:35].
- The great players are "always deviating from that note and coming back to it" [06:28]. Exercise for musicality, long and short (https://www.youtube.com/watch?v=z_wlIovfN04 and https://www.youtube.com/watch?v=Zw7vrIpRwqM)
- The Miles Davis rule: "never finish anything," which can be as simple as leaving off the last note [00:39]. Withholding resolutions makes the one you do play land harder [05:10].
- The short video gives a pattern to practice this week. Start on the note you want to end on, fifth finger, then down a third three times and down a whole step, then up a third three times and down a whole step, "third third third whole step" both ways, all white keys in C major [00:49].

- Part two of the video is motivic development [07:20]. Take one melodic shape and repeat it in a new harmonic context, the same fingering working over C Dorian and F7 [08:41], then sequence it descending three times through the modes and answer the fourth statement with a variation that resolves unexpectedly [09:54].
- The move that chains ideas: build the next phrase out of the note the last phrase ended on [12:16].
- "If you start by trying to play a bunch of notes it will not be music, it will just be a bunch of notes" [14:05].

At the piano
Work in C minor with a static left hand, root and fifth, so nothing distracts from the right hand. Metronome at 60, clicking beat one only. Play a three-note cell: B, C, D, a half step up then a whole step up, the same shape Greg used, so you can compare your results to his.
Run the eight techniques from the source course on that one cell, slowly enough that you hear each one as music rather than as an operation.
- Transposition. Same intervals, new pitch level. Through all twelve.
- Inversion. Every ascent becomes the same-size descent. B, C, D inverts to B, B♭, A♭.
- Retrograde. D, C, B. The source course warns that in a tonal context a reversed motive "often sounds completely unrelated to the original" (Source course, Lesson 3). Play it anyway and hear whether that is true for your cell.
- Augmentation. Double every value. The cell becomes a slow theme.
- Diminution. Halve every value.
- Fragmentation. Keep only the half step and sequence it.
- Sequence. Repeat the cell immediately one scale step lower, exactly as Greg had you do it live: "instead of starting on C, start on B."
- Intervallic expansion and contraction. Keep the shape up-up, stretch the intervals to a fourth and a fifth, then squeeze them to two half steps.
Greg's decision point sits on top of all eight. Every transformation is either literal, keeping the exact intervals and going wherever they land, including out of the key, or diatonic, keeping the shape and letting the key size the intervals. He named both in your lesson: "this is the tonal option" against "you can make it literal," and then "you can cycle between those two as well." Play four bars literal, four bars diatonic.
Tempo rule, in his words: "Do it slow enough you can think about exactly what you're doing. You shouldn't miss any note when you do it slow enough."
Exercises
Greg's first two master-class exercises come before the rest of these, and they run with a metronome or drum machine at 50 to 70 BPM. His instruction is explicit: "Do not speed up until you have fully internalized each one."
1. One-note rhythm solo
Do. Over an F blues, solo using the root only. One pitch, nothing else. State a rhythmic idea in bar 1, vary it in bar 2, and make everything after that relate to those two bars. If you do not have an idea, do not play. 55 BPM.
Done when: you can play a full 12-bar chorus in which a listener could clap back your opening rhythm, and every silence was a decision rather than a stall.
2. Five-note story
Do. Same F blues, same 55 BPM, now with scale degrees 1, 2, 3, 4, 5 and the ♭5 optional. Treat each degree as a character. Use the ♭5 to 5 and the 2 to 1 resolutions on purpose. Keep the bar-1, bar-2, bar-3 rule running. Greg's rule from the master class: "Variation is important, but arbitrary variation muddies the story. You can either vary intentionally or repeat exactly. Both are valid. Arbitrary variation is not."
Done when: you can play a chorus and afterwards say, phrase by phrase, whether each one was an exact repeat or a deliberate variation, with no phrase you cannot account for.
3. The twenty-idea count
Do. Take the cell C, D♭, F from the source course. Spend twenty minutes generating distinct ideas from it using the eight techniques and combinations of them (inversion in augmentation, fragment plus sequence). Tally each distinct idea.
Done when: you have more than thirty tally marks. The source course sets twenty as the floor and thirty as the sign that you are thinking motivically.
4. One cell, one tune, out of time
Do. Pick a tune you know. Play through the whole form using only your three-note cell, out of time, choosing a target chord tone on each chord before you play the approach. Say the target out loud one chord ahead.
Done when: you complete the full form without adding a fourth pitch class to the cell, and you can name the target one chord before you reach it.
5. The chain
Do. Play the cell. Sequence it down one scale step with the identical pattern. Land somewhere and outline the note you landed on. Reapply the down-a-step move to the new idea and continue in that direction. This is the chain Greg walked you through at 1:15 in the lesson.
Done when: you can play sixteen bars in which every idea is traceable to the one before it, and you can say out loud which transformation connects each pair.
6. Literal against diatonic
Do. Record two takes of eight bars on the same cell, one entirely literal, one entirely diatonic. Then record a third that alternates every two bars.
Done when: you can hear on playback which take is which without checking your notes, and the alternating take does not sound like a mistake.
Compose
Write sixteen bars of piano music, one line in the right hand over a simple left hand, generated entirely from one three-note cell.
Constraints. Every right-hand pitch belongs to a transformation of the cell and you can name which one. At least five of the eight techniques appear. At least one transformation is literal and lands outside the key. The last four bars use fragmentation only. Notate it in Sibelius by hand, mark each transformation above the staff, then play it.
Checkpoint
- You can state the difference between a motive and a melody, and say why the incomplete one is the useful one.
- You can perform all eight development techniques on a cell you have never seen, at sight, slowly.
- You can improvise a chorus using one cell and land on a chosen chord tone at every chord change.
- You can say, of any two adjacent phrases in your own playing, what transformation connects them.
- You have sixteen bars notated with the transformations labeled, and you can play them.

Greg's own written version of everything in this lesson: the Three Pillars, the bar-1 / bar-2 / bar-3 rule, space ("If you don't have an idea, don't play"), and repetition as power. Exercises 1 and 2 above are his, at his tempos. Read it first.

The definition, the two components of motivic identity (interval content and rhythmic profile), the simplicity principle, and the eight techniques with Bach and Beethoven worked out. Read it before Exercise 1. https://composition.gregspero.com/library/garnett-course.pdf
- Bach, Fugue in C minor, WTC I, BWV 847. Get a score. Play the subject slowly, identify every interval, then trace it through the fugue. One correction: the actual subject is a continuous figure, C, B natural, C, G, A♭, C, B natural, C, D. There is an eighth rest before it, on the downbeat of bar 1, and no rest inside it. The source course's prose describes a line that begins with a rising half step and leaps up a minor third to E♭. That is the tonal answer, which enters in the top voice at bar 3 as G, F♯, G, C, E♭, G, F♯, G, A, not the subject. Trust the score. The lesson the fugue teaches survives the correction intact, and it is the one that matters. Two bars generate the entire piece.
- Beethoven, Symphony No. 5, first movement. The source course's claim to test by ear is that the lyrical second theme is built from the same short-short-short-long cell as the opening. Listen for it specifically.
- Sonny Rollins, "St. Thomas." The source course calls it "one of the great demonstrations of motivic development in jazz," and contrasts Rollins with Parker: "Parker's solos are additive (new material constantly arriving); Rollins's solos are developmental (the same material constantly transforming)" (Source course, Lesson 3). You want the developmental one.
