Hello friends, I live in Brazil and I just wrote some exercises based on those in Clarke Technical Studies for Cornet.

This first book on this matter focuses the major scale and its modes as well as the pentatonic scale. Soon the 2nd volume with the Whole Tone scale, Diminished and Melodic Minor will be published.

It is 230 pages long [less than 3MB in PDF]. The text is in Portuguese, BUT there are tons of exercises to your appreciation. Please send questions and I will be glad to respond. It may be downloaded for free. The link is in my blog.

I'd like you post your comments and suggestions.
