Use Case

Play along with chord progressions, not just fixed backing tracks

Paste your own changes, open an exercise, or tweak an existing chart and hear the rhythm section adapt immediately. It is a practice workflow built around harmony, not around static audio files.

Turn a progression into a playable practice session

If you are working on ii-V-I lines, a turnaround, a modal vamp, a blues form, or a custom reharmonization, you usually do not need a full song page first. You need to hear the progression, set a tempo, and start playing.

Chord Progressions lets you type or paste a chart and immediately play along with piano, bass, and drums. Because the accompaniment is generated from the chart, changing the harmony changes the band too.

Useful practice patterns

  • Technique drills such as ii-V-I in all keys or cycle studies.
  • Ear training on short harmonic cells you want to internalize.
  • Comping practice with piano dropped out or reduced in the mixer.
  • Improvisation work over a vamp, turnaround, or reharmonized section.

Why this is better than a generic loop

  • You can change chords instead of hunting for a new track.
  • You can choose tempo and feel for the exact thing you are practicing.
  • You can save custom charts locally and come back to them later.
  • You can move from a tiny exercise to a full standard in the same app.
