I7 · IV7 · V7 in the key of C
Four whole bars of home before the IV — the patient version every jam starts on.
Four bars of 12-bar slow change in the key of C, written I7 · IV7 · V7 and played quarters over a backbeat groove at around 92 beats per minute. The chord shapes are below, and you can hear the whole thing play — and slow it down — without an account.
Opens in the Progression Lab. No account, nothing to sign in to — ten minutes of playback a day, and an hour with a free account.
