As mentioned in another post in the recording forum, I have a renewed sense of needing to refine my playing technique and to play more technical stuff, after spending the last decade "noodling around'. Here are some boundary conditions/constraints: Age: Dunno if this is one, but I'll list it anyway. I'm now into my 30s. Time available: I can spend about 1.5-2 hrs everyday on average, and probably 4 hours each day on the weekend on all things music. Or roughly 15-20 hours a week on music. Those are pretty much my constraints. I have space, gear etc. and I'd classify myself as an intermediate guitarist. And here are my goals: - Clean up my lead playing to avoid sloppiness - Tighten my rhythm playing to play stuff like Textures etc. - Be able to break into the realm of shred, say 16th notes at 150bpm, if I had to quantify it. Let's say I'm currently around 100-120bpm or thereabouts. Given my goals and my constraints, how would you recommend I make the best and most efficient use of my time and measure progress? And assuming I stick to this path and my goals don't change, what is a realistic timeline when I should be getting nearer to breaking that speed barrier? I know this depends on the person, but on average would it be on the order of a couple months, several months or years? Cheers!
