Okay, I'm a bass player and for a long time, I've been wanting my guitar playing friend to play melodies and leads. Now recently, he's gotten a bit better at writing leads once he has learned the scale for it though, he isn't good at picking up leads by ear.

Now recently, I've been writing a lot tapping solos and recently I thought it'd be a good idea if he wrote a lead on top of it. Unfortunately, he can't find the write notes by ear. I was wondering that if I uploaded a video of me playing my tap, or tabbed out my tap, if someone would help me find a good guitar scale for leads and melodies, or just a good scale for my tap?
