That's cool. How fast can you identify the key? How fast can you jump up or down an octave or mimic the melody? Do you understand C-A-G-E-D theory and how it can improve your improvisation? Can you take the melody / harmony apart? And put it back together again? Do you want to know more about rock, blues and metal music theory (scales, triads, the geometry of the fretboard, improvisation, etc.)? Do you have good materials or techniques to share?
Like what you're doing now, recommend a good teacher! Or a good gear technician or instructional website.
Is there an event going on we should all know about?
Share your cool ideas and resources; let's see how this snowballs into a tighter DC music community.
