Specifies the scale type to use
for the composition. The scale determines the set of pitches used by fractal composer
to generate the piece.
Generally speaking, your germ should only contain notes from the selected scale.
Accidentals are allowed, but will usually create excessive dissonance, as they
propagate throughout the piece when self-similarity is applied.
If you wish to minimize dissonance, consider using one of the pentatonic scales.
This will eliminate the most dissonant intervals (minor seconds, major sevenths
and tritones), as long as all the notes in your germ are part of the selected
pentatonic scale.
If you don't know what any of this means, try the major scale.
This is the most commonly used scale, found in tons of classical and popular music.
