    Build a small, repeatable routine

    Choose a progression and start at a comfortable tempo. Play along on your instrument, sing the chord roots, or name the notes before each change. Each chord lasts one four-beat bar in 4/4 time.

    Changing the key transposes every chord together: a C–G–Am–F exercise becomes D–A–Bm–G in D. The chord qualities, scale degrees, order and four-beat durations stay the same. Loop just the bars that need attention, then return to the full progression.

    What you hear and save

    Playback uses simple synthesized tones and a beat click, not sampled piano or harmonium audio. Press Start to enable browser audio. Stop, Reset, editing settings or leaving this page cancels the session. A session plays at most 16 loops and stops when the page is hidden.

    Named practices stay in this browser’s local storage; they are not synced between devices. MIDI contains the selected, transposed bars once at the chosen tempo, without the count-in or repeat count.
