Tempo, Key and Form

Give tempo as a number, key by name and form as sections; "flowing" buys no structure.

The problem

Prompts that ask for "rise and fall" or "layers" leave the model guessing. Tempo, key and form are three parameters that can simply be stated, and stating them gives structure a skeleton.

How to write them

Give tempo as a number and unit, such as 86 BPM; for changes, say which section moves and to what. Name the key, such as D minor, and state it when atonality or modal colour is wanted. Describe form with section names, such as intro of eight bars, verse, chorus, interlude, chorus, outro, plus lengths and repeats. Write emotional change separately from structure.

Practice

Fix the form first, then prompt section by section. Say how sections connect: straight in, crescendo, or silence. When material returns, write "return to the first section's material". After generation, check whether the sections actually appear and add whichever is missing. Tempo changes are safer generated per section so the model does not average them away.

What to listen for

In the traditional tune, the steadiness of a simple form; in the rondo, theme returns against episodes; in the variation movement, how the time scale unfolds. Clear structure keeps a generation from running flat.
