Rules
01
Half step (semitone) = smallest interval in Western music = 1 key on piano = +1 MIDI
02
Whole step (tone) = two half steps = +2 MIDI
03
Enharmonic equivalents = same pitch, different name (C♯ = D♭, both MIDI 61)
04
On piano: half step = adjacent keys (including black keys)
05
These are the building blocks of all scales and intervals
