To answer the tenor question.....Tenors started playing more notes when Tom Float started teaching the Blue Devils in 1982.Before then the snare line had all the "notes".In 82 Tom started giving his tenor line a "snare book" approach.(ie alot more flams)Listen to Paradox 82,83 and you'll hear what I'm talking about.The tenor line at devs from 82 on has been known as the Q-5.Even though there have been many fine tenor lines from many corps(you'll find that 90% of em have been taught by a BD Q-5er)ie Mike Stevens Q-5 89-90 began Cadets tenor line success in early 90s,Vern Johnson Q-5 88-92,taught VK 93-94,just a few examples.)Anyway,The Blue Devil Q-5 I believe has been a kingpin in the evolution of tenor drumming since 1982.They to this day continue to be arguebly(sp?) the most respected line on the feild.And for you Cadet 2000 tenor break fans....John Burbank VK 93-94(also a student of the Q-5 way of tenor drumming through Vern Johnson).I hope this helps. :)
