[Harp-L] playing clean AND fast

[brian stear]

I just recently did an uptempo video:

I had trouble getting some of the fast stuff during the solo clean enough to hear distinctly. My question to all of you is: Are there any tips or techniques for playing fast cleanly, except for starting slow, and speeding up? I'm hoping there's some tried and true practice regimens that I might not know of.Thanks for any and all help!
