Hi Maurice,
Please excuse me, as a non lapper, chucking my egg into the pot:oops:
The reason being, I was chatting to Dougie Stevenson at Gartcosh the other night about practice technique. Now Dougie's a black belt, 8th dan lapper, whose latest album, 'Scottish Chillout', is now available from all the usual channels(shameless plug).
Anyhow, he was telling me that the first thing he does when he sits down at either the lap or the Dobro, is to make up little tunes, where he's trying out new positions or new picking patterns, and then when he has a melody he likes, he transposes it to different keys. Then when he finds himself sitting in, or jamming, he sticks pieces of these made up tune's in, as he sees fit.
No scales or chord inversion practice for him, everything is melody based.
At the Gartcosh meetings he never passes on a round robin tune, even though he's never heard it before and invariably ends up amazing us lesser mortals.
So, I reckon your own method of making up riffs and melodies is sound practice. It's all gravy
That's it, my egg's done!
