HOW TO PRACTISE IT
Six steps to a clean loop.
- Play each chord on its own: F, F/A, B♭ and C. Press play on the chord card, then match the sound.
- Mandolin frets are close together, so reach with the fingertips and press each pair of strings evenly.
- Set the tempo to 60 BPM and play the progression with one chord per bar. Bring out the bass note of each chord a little more than the rest.
- Strum down on every beat, then try the bluegrass “chop”: a short, muted strum on beats two and four.
- Raise the tempo to 80 BPM once you can play the loop three times without stopping.
- Record one take, listen back and check for a bass line rising one step at a time.
Listen for
Aim for a bass line rising one step at a time. A common mistake is playing the root in the bass on the slash chord.
