Belated Practice

On Friday I practiced an hour and a half. I played through Clarke's 2, 3 and 4. I then did chromatic scales major and minor starting major from C to A then minor A to F sharp. I then did Charlier studies 14, which I sometimes have trouble getting through all the way I usually tire and need a break, and then Charlier 2 which I find I keep forgetting the D and G flats and only the first 24 bars. I then worked on the Haydn Concerto. I got throguh all the first page and about half the second page. I find the range is tiring before I can get very far by the time i do what i can about 4-5 times my lip can't hold up the long G's and A's.
