One note, every day.
Cold recall · first of the day
Before you hear any music, hum your C3 and hold it steady for about three seconds. Commit before you check.
Log a tuner reading
Hum into any tuner app, then enter how far you were from the nearest C.
Imprint · 30 seconds
Hum along with the true C. Notice where it buzzes in your chest or throat, and how it sits in your range. Those sensations become your anchor.

Each note is heard alone. A short noise burst plays first to wipe your short-term pitch memory, so you can't compare against the previous note.
Keys: C for C, N for not C, R to replay.
