So I heard many people saying you should sing or hum something over the riff where you want to write a solo and then transcribe it on guitar, because then you would get an ear for music. So this seems logical and also believe that it works if you do it quite often. So but if I do it this way the solo or a lick sounds OK, but If I just try something within the scale I´m in, then most of the time it sounds better than the humming thing.

So my Question is: Should I continue soloing like I do it now, which at the moment works better and is easier for me, or should I better try witing a solo by the other possiblility?

How do you guys write your solos and do you know how the famous guitar heros write and wrote theirs?
