Exactly and that's where Tag's comment about being able to play "Happy Birthday" is so relevant. It's not about that particular song itself but the intervals, and Happy Birthday works because it's a melody everyone - even non-musicians - can hear in their head and hum or sing. Don't like it? Go with the Star Spangled Banner instead (Worked for Jimi and I guarantee he didn't learn it from a copy of Guitar For The Practicing Musician while waiting to go on stage at Woodstock LOL).. Think about that: non-musicians being able to hum or sing a song perfectly, and that's the goal of any improvising player I would think - being able to play on your chosen instrument what you are hearing in your head. Because if you're not doing that, or not able to do that, what exactly are you playing? Patterns? Scales? When I picked up the guitar back in 1983 I thought what was standing between me and making music was the fact that I hadn't memorized enough tablature. What a horrifying, dead end mindset.. And what a revelation the "Happy Birthday" idea would've represented. So now I'm trying to make up for lost time.
