I was reading 10 minute guitar workout and I'm doing some exercises to understand how to create a Cmaj6 chord for example, from a C major chord.
When I was reading online for tabs to understand which notes were the 4th, the 6th note etc from the C major octave I stumbled upon two websites with two different tabs for the first octave, although the notes are the same which makes both of them correct I assume:
The second scale sounds better to me for the D note, since I prefer it played on the E string 5th chord than open on the D string.
Could you tell me why I see different tabs? Is there a source you recommend for me to use a reference for this kind of exercise where I can see the notes a major scale is composed of?
Thank you in advance.
