An announced iPhone and iPad app that plays piano, upright bass, and drums against chord charts while responding to a musician’s playing.

Landing page captured for the 2026-08-30 issue.

Field notes

PocketTrio is presented as an accompaniment system built around chord charts rather than fixed click tracks. The page names six rhythm vocabularies, from Bossa Nova to Afro 6/8, and gives users control over voicings, comping density, fills, per-instrument mix, and EQ. Its proposed listening mode analyzes microphone input locally and adds the player’s note over the trio’s chords. The App Store release is described as forthcoming, so the public page documents an intended workflow rather than an accessible working product.
