Like the Klosé book for clarinet and the Arban book for trumpet, this is the "standard" method for saxophone. It includes 320 pages of exercises, etudes, solos, duets, cadenzas, text, etc. A must for serious saxophonists!
Definitely one of the most enjoyable practice books , I didn't feel overwhelmed by the music theory at the beginning since I needed a major refresh. 5/5 would recommend
