Help!
I've been jamming at a local bar on open mic night for about 1 year. Now, I feel like getting out and playing in other bars with different people.
I-IV-I-I
IV-IV-I-I
V-IV-I-V
This is the progression that I'm used to ... whether it be straight triads, or any combination of 7th or dominant chords w/ extensions. Usually I can play whatever chords I choose for a rhythm, and the better players just watch me and immediately know what modes to use for their solo. The rookies just stick to minor pentatonic or the blues scale. Is it rude to play (dom 9,11,13) chords or (dom7#9) without saying anything about it? Most of the time there is no discussion on the specifics other than the feel of the song.
I'm not sure if this progression is universal to all open mic jams, so what else do I need to practice? Is there anything I should know before I set foot in another bar?
I thought learning the blues was going to be easy, but there seems to be an endless amount of surprises that come up on a regular basis.
I'm pretty good at adapting to new stuff, but I definitely sweat for the first couple go arounds.
I'm just a little intimidated to go elsewhere and play ... i'll probably be ok, but I kindly ask you fine folks for the "MUST" knows of da' blues.
