StaffGlow

StaffGlow presents short rounds of 10 prompts on a staff.

Choose a mode:
• Notes — name the letter (C, D, E, F, G, A, B) for a written pitch
• Intervals — name the span between two written pitches
• Key signs — name the key from the count of sharps or flats

Pick Starter, Middle, or Advanced. Switch treble and bass clefs at any time. Each answer is checked at once, with the correct letter or name shown after you pick.

A running hit count, miss count, and streak stay on screen during the round. After 10 prompts you see a hit rate. If the rate is under 60 percent, StaffGlow suggests staying with Starter until the pace feels steady.

The Atlas page maps every line and space in view, including ledger lines above and below the staff, plus sharp and flat marks. Marks stay on this device. There is no share or export action.
