Watch the Pitch & Note Choice online guitar lesson by Robbie Calvo from Lick Logic
In Western music, we have organized the pitches we use for improvisation into scales. The chords that we play over have been instructed by those scales. We then have to decide how to target, outline, or color those chords and progressions using the pitches we are given. The note choices you make in conjunction with the rhythms will become your personal voice. Remember that and start to discern the sounds you like and favor over other notes. Some guitarists enjoy the dissonance of outside playing, while others like myself stay within the context of consonance and rich melodic motif based ideas. Start to make really conscious decisions about the note choices you make. Just because there are 7 notes doesn't mean you have to use them all, and also having a clear understanding of chord tones and tonal centers is going to help you target the right choices quickly. Don't be afraid to be yourself!
