This is a simple blues in the color " indigo " - I have played both instruments the piano and the guitar. The piano was played in a special moment you can see in the picture. Below you find the original piano track I have recorded some time ago.

Beautiful Professor ... just beautiful.

Is there a TAB available, or did you just play ad-lib? If my fretboard lessons are progressing, and some knowledge is being absorbed, would I be correct in guessing that that was played in D minor? I had trouble establishing if you were playing Pentatonic Shape 1 on either fret 5 or fret 10 ..... I gambled on 10? Please put me out of my misery ... whether good or bad news.

Thanks Phil,

sorry there aren't any tabs available. But the key is F major which are the same notes as D minor. Just an other root note. Check those patterns here. They work out fine and are basicly the ones I used.

E |----------------------------|-----5--6--8----------------|
B |--------------------5--6----|--8-------------------------|
G |--------------5--7----------|----------------------------|
D |-----5--7--8----------------|----------------------------|
A |--8-------------------------|----------------------------|
E |----------------------------|----------------------------|

----------------------------|--------------10-12-13------||

-----10-12-13---------------|----------------------------||

Cheers HP .. you're a gentleman!!

So I had the correct shape and position, I just should have used the low E strings' 13th fret F (pinky), or A strings' 8th fret (pinky) as the root notes?

Well the low notes are not used here.
