Eric Clapton songs have always intrigued me and, well, intimidated me. I haven't really been a lead improv or blues player - but have focused more on rhythm on country and folk music. But, as a gigging musician, I'm being challenged to learn new stuff. So, I'm now working on Layla.
Individually, the song isn't complicated - chords are pretty straight forward for the chorus and verse. The solo work is based on a Dm pentatonic scale with some diatonic notes added.
Here's my approach to learning it.
1. I know the song from listening to it, but I still start here. Listening to the original artist (Eric Clapton Unplugged). Then I simply sing along with it until I have the phrasing of the lyrics.
2. Check Youtube to see what covers are out there and if I can find Eric's live version, watch those to see the chord voicings.
3. As a reference, I'll pull the chart from UG or other sites.
4. Start playing along with the video version to cement timing
5. Drop the videos and go it alone until I have it down
For the solo, I don't use tablature - I can normally find a 'how-to' for most of the solos - and for Layla, there are plenty. I'll get the gist from those and then see if I can tackle it. I don't shoot for, "Note for Note"; rather - the feel and the recognizable licks.
Last stop is to work on the Looper timing and 'master' it. The harder the song, the longer before I play it live - this one will take me a month I think.
Good and insightful stuff! Making songs my own takes time but even so, the songs are always changing. Tempo, voicings, rhythm patterns, arrangements, whatever mood I'm in basically also, will affect my performance.
