http://fastpianolessons.com for some more great blues licks!
This was a paid request! It covers the first 15 seconds of Chris Thomas King version of Everyday I Have The Blues. There is a really cool piano solo for the first 25 seconds of the recording and then the rest of the band comes in with the vocals.
The introduction is filled with great blues licks. Learn a few of them and then transpose them to different keys! Take the time to learn one of these licks really well, so it becomes natural.
