Dauprat’s 20 Duos for French Horn or “20 Duos Pour Cors” was specifically written to practice transposition. Each of the 20 long form duets are written for horns in different keys. F and Eb in one duet, leads to D and G in another. The bottom of each duet shows you the first measure of each part as it would be played on horns of different keys. A lot of care has been given to ensure that players who are learning to transpose get off on the right foot.
Don’t let the French title scare you off. After a short foreword in French, you are left with 40 pages of wonderful long form duets by one of the masters of the instrument. This is a book that should be in everyones collection.
