I7 · IV7 · V7 in the key of B
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 B, 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.
