The spectrum map
Memorising a pitch
Finding a pure tone from memory trains frequency precision.
A pure tone holds a single frequency. Finding it on a slider forces you to keep its pitch in memory and compare: exactly what you do when looking for a frequency to correct.
Work by bracketing: too high, too low, then narrow down. Errors are measured in semitones and percentage of an octave, the way the ear perceives them.
Pitch memory improves quickly with regularity: a few minutes a day beat one long weekly session.
Listen for
- The pitch, not the loudness: high tones seem more present.
- The moment the two tones "merge".
The classic mistake
Sweeping the slider at random: listen, remember, then move in large steps before closing in.
