This legato study has a pretty cool melody with a nice dynamic octave change at the bridge. As with any legato, the challenge is to play it perfectly in time. It’s not particularly fast, but maintaining equal durations across all 8th notes will take practice. Adding some overdrive/distortion will make it easier as notes will sustain longer and you won’t need as much pressure to sound a note. As an extra challenge, try the Celtic backing track with an acoustic guitar!
