SMART CHORD PROGRESSIONS Build chord progressions using the grid editor or the interactive Circle of Fifths, a visual tool that highlights diatonic chords in your selected key, so you can see at a glance which chords belong together.

Your own band, ready to play whatever you're working on. Backing Band turns a chord chart into a real-sounding rhythm section — drums, bass, piano and guitar that actually groove — so you always have something musical to practice over. Lay out the changes to any tune, pick a feel, press play, and start soloing. WHAT YOU CAN DO • Build any progression — enter the chords, arrange your sections (intro, verse, chorus, solo, turnaround…), and the band plays them back. • Pick a style — swing, bebop, shuffle blues, slow blues, classic & hard rock, funk, neo-soul, bossa nova, samba, reggae and more, each with its own groove, feel and arrangement. • Make it yours — set the key, tempo and feel; reshape the groove section by section; balance or mute instruments in the mixer. • Play and practice — loop the form, build your solos, lock in your time, and train your ears over a band that breathes. BUILT FOR PRACTICE, NOT A STIFF LOOP Real intros and endings, fills between sections, and a rhythm section that lifts behind your solo instead of looping the same bar. Whether you're shedding ii-V-I changes, grinding the 12-bar blues, or running a pop tune, the backing actually feels like players in a room. GENRES Jazz · Blues · Pop · Rock · Funk · Soul · Latin · Reggae — with a growing library of ready-to-play demo songs to start from or remix. FOR EVERY PLAYER Guitarists, pianists, horn and reed players, bassists, singers, students and teachers — anyone who learns faster with a band behind them. Download Backing Band and never practice to silence again.
