Augustin Hadelich’s complete solo Bach Largo. Opens free-playing review with pitch, dynamics, replay and held-note tone analysis. Pitch follows held-note centers; quick ornaments are not scored as tuning errors.

Synthesized exercise for the selected mode. An ascending and descending phrase with tuning errors, a short trill, and a rise and fall in dynamics. The swell peaks later than planned. Compare the pitch palette and dynamics report. No microphone needed. Opens a review for this mode.

Intended dynamicsShape

Relative shape from the first to last audible sound. Custom points are evenly spaced through the take. This does not read dynamics from your score.

Tiles show a recent weighted tendency for each pitch; the highlight follows the current note. In the combined view, the latest octave is shown. Blue = flat · Green = in tune · Orange = sharp. Review still uses the mean across the take. Bars extend left for flat and right for sharp, with zero at the center (±50¢ range).
