I found the scale and arpeggio studies for clarinet (and adapted for saxophone by D. Hite) by Friedrich Demnitz very useful in learning these instruments. The studies are melodious and use the full range of the instrument, but they are not technically difficult. I assume that similar material is available for the recorder, and I wonder whether anyone could make any suggestions. Thank you.
Thank you for the justflutes list of recorder studies. Several of them are very suitable for my purposes.
As for the Rose studies, I might leave them alone for the time being. The ones I know were written for the clarinet, and the huge range of the clarinet would require extensive adjustments for the recorder, although parts of them could be played as they are. They are rewarding for the clarinet player, though.
