Key pitch trace
Start singing and watch your voice move through the current key. Type a degree pattern to add guide targets.
Use scale degrees like 1 2 3 4 5 6 7 8. Separators can be spaces, commas, or dashes.
For other octaves add d (down) or u (up): 5d is the 5 below the root, 2u the 2 an octave up, 5dd two octaves down; 9 and up keep climbing.
