I was trying to separate out what I'd learned from what I already knew.
Without wishing to start another pointless thread, the first video really highlighted one of the benefits of reading music, as Scott's 'groove grid' is instantly accessible in the form of the rhythmic aspect of music notation.
I think the real eye-opener for me is in the second video on the subject of note choice.
1. Chord tones - no argument there.
2. Chromatic approaches - see below
3. Scale tones
I would not have thought about putting chromatic fills above scale tones, but thinking about some of my favourite players (Jamerson, Rainey) that is bang-on correct. There are times when you use a short scale run to link chords, but it can end up sounding a bit vanilla if you overdo it, whereas chromatic links sound that much spicier. Jamerson famously used the naturals on the open strings as chromatic passing notes when playing in 'flat' keys.
And on the third video, the concept of 'stings' had just never occurred to me.
So those are my own 'key learning points'.
