I have been working on a "manual" of sorts. One of the sections that is the most fun for me, and I enjoy working on myself is that of "patterns and scales". I often find students being pushed to do 2 octave scales as a necessary evil to band method, when in fact most music we encounter uses small sections of scales and collections of patterns. Scales are great, don't get me wrong, but variety is the spice of life, and 5 notes are pretty powerful (especially when you link them into other groupings.)
Here is a link to one of the exercises coming out of the manual I am working on.
A breif about that manual, it is being designed around "marching" instruments. Which is mainly to say, which I need to note as a horn player, that the books harmonic and range content is based around instruments one find in marching bands. Look for that soon.
