Not enough practice time.

Finally got round to picking up the 'Cello again today, even if it was only for an hour. Didn't really get much done, except a few scales, and arpeggios to limber me up. I'm having a lot of trouble with the Eb Major scale, and D minor, both two octaves. I know exactly what to do, but as far as intonation is concerned, it's not happening. It's important as well, because the first Bach prelude has a few extensions and troublesome (for me) shifts. Either way I'm still slogging through Bach. My bowing is troubling me as I'm playing every phrase nearly entirely slurred (which is how I like it), but I know this is incorrect. The intonation is fine, but I notice I go ever so slightly out of tune without noticing, and am promptly reminded upon playing an open string. Anyway. It' s late. I gotta be up in 6 hours.
