I've returned to playing Cornet after a few years and I'm currently working through Arbans 14 studies and wondered what the 'order of difficulty' would be. Appreciate this is totally subjective and one mans No.12 is anothers mans No. 4... and each one tests different things to different degrees. eg: No. 12 is currently on ABRSM Grade 7 for Cornet, and No. 10 is Gd 8 - but I reckon playing No. 10 is harder. Would be interested to hear thoughts.
