Swing and shuffle
Play swung eighths and a shuffle feel, and read how they are marked.
Two players can play the same written eighth notes and sound completely different. The difference is whether the pairs are even or long–short.
Swung eighths
In a swing feel, pairs of eighth notes are played long–short instead of equal; they are swung eighths. The usual reference is the triplet: the first eighth lasts the first two notes of a triplet, the second the last one, a 2:1 ratio. In real performances this swing ratio varies with tempo and style: wider at slow tempos, closer to even at fast tempos.
How it is written
Swing is written as ordinary eighth notes, with an indication at the start: “Swing”, “Shuffle”, or a small equation showing two eighths equal to a quarter-note triplet followed by an eighth-note triplet. The same rhythm written in 12/8 is how some slow blues are notated.
Shuffle is a long–short feel built on the triplet. It usually has a more insistent, even triplet pulse, common in blues, boogie and rock. The two terms overlap and are used differently by different musicians. A precise, universal distinction is not established, and it is not taught here.
For the bass
The long–short feel must match the drums’ ride or hi-hat pattern. Straight eighths over a swung groove sound wrong immediately.
Play eighth notes on the open A with the triplet click from lesson 11.3, playing only the 1st and 3rd note of each triplet. That is the swing feel. Then play a root–octave line over C – F – G (one bar each) with that feel.
