David's Tip of the Day: V-IV-I area in Accompaniment
A student asked about the V-IV-I area (Bars 9-11) part of the 12 Bar Blues in regards to accompaniment. It's commonly an active area and he was wondering how to approach this area without grabbing too much attention (interfering with the vocals). Here are some general guidelines for everyone. Remember... no rule book exists, but here is what I have personally observed in my studies...
1) Playing Chord Tones is best
2) Repetition is better than activity
3) Sequencing from the V Chord (Bar 9) to the IV Chord (Bar 10) can be a good idea (thematic). The IV Chord is generally used as a transition back to the I Chord (Bar 11), so don't over-analyze Bar 10, you won't always be able to nail it down as being a "IV Chord" idea... many times it's used as a transition to the I Chord (Bar 11) and that's all.
4) The V-VI-I area is traditionally a more active area of accompaniment (and soloing), so as long as you're leaning towards more chord tones, you're generally safe.
5) Copy the licks I present to you in each example and study, they will give you references points (and licks to play NOW).
6) Study what other harp players have done here, they will give you more reference points (and more licks to play).
7) Finally... do your thing. If the vocalist doesn't look back in disgust, then you're good ;-)
