ChartBand: Jazz Backing Tracks

Photograph a lead sheet from your own fake book. A band plays it with you, and the bar you're hearing lights up on your page.
Walking upright bass, jazz drums, comping piano: real recorded instruments with the feel of real players. No generative AI.
98% accurate chords, read on your iPhone or iPad. Your pages never leave it.

YOUR PAGE, NOT A TYPED GRID
- Scan the lead sheets you own, or open one as a PDF: printed fake-book pages or neatly hand-written charts
- Chords, bars, repeats and endings, read right on your device
- The cursor follows the band across the page you photographed: your edition, your pencil marks
- Two tunes on one page, or a tune that runs onto the next page? ChartBand asks
- Prefer a clean grid? Switch to the chord chart any time

A BAND THAT REALLY SWINGS
Every sound is a recorded instrument. The playing is live: comping, groove and swing measured from real players, fitted to your chart. No generative AI.
- Walking bass, or bass in two
- Pick your drummer: Classic, Easy Swing, Hard Swing, Brushes or Bossa
- Pick your pianist: Session comps like a real player behind a horn, plus five more comping styles
- Swing, ballad, bossa nova and jazz waltz
- Upright or grand piano, intensity from calm to hot, and a mixer to mute your own instrument

PRACTICE THE WAY YOU NEED TO
- Loop any bars, slow the tempo down, count in
- Transpose to any key, or pick Bb, Eb or F and the chords show in your key
- When the app has read the melody on your page, it writes it out in the new key
- The keyboard lights up every voicing the piano plays: simple, inversions, rootless, drop 2, two-handed
- Guitar: chord boxes right on the chart, and tab for the melody
- A shelf of practice exercises (ii-V-I in every key, turnarounds, blues, rhythm changes) so you can try the band straight away

FOR STUDENTS AND TEACHERS
Practice the tune from your lesson, from the same page, in your instrument's key, at any tempo. Teachers: ask about App Store offer codes for your students at chartband.com/teachers.

PRIVATE BY DESIGN
Your pages are read on your device and never uploaded. No account, no ads, no tracking. Sharing a tune copies a chord-only chart, never your photo or the melody.
