Thanks for the interval advice! I have heard a balance of 'note-reading' and 'intervallic-reading' is good.
I'll certainly give that a try!
I know chords pretty well. maj, min, dim, dim7th, aug, maj7th, min7th, dom7th, sus4, sus2, 9th etc..., I know scale degrees I, ii, iii, IV, V, vii, viiº for major scale. Tonic, Supertonic, Mediant, Subdominant etc... and I know my key sigs and relative Maj/Min etc...
The problem is, I know all this fairly well (as most pianists should), yet I have trouble trying to incorporate all this into sight-reading music. Maybe I'm trying to hard and making it more complex than it needs to be.
But thanks for the advice!
