Well, actually singers can learn lots of things from master musicians, but I want to highlight this one today: The secret of the light-just-right touch. Great musicians know that pressure matters, for instance...
What master musicians know and practice is the secret of the light-just-right touch which coaxes the brilliance out of their instruments, gives them control of pitch and dynamics, allows for easier movement upon their instruments. Even when bearing down for more power, these musicians still 'pull their punches' and never play as hard as they can upon their axes.
This secret is directly applicable to singers. We're talking about the light-just-right touch of air applied to the vocal cords. Our voices need adequate and consistent breath support, sure, but breath support that is CONTROLLED. With this balanced breath pressure we get much better vocal tone, more technical ability, we record better and we have the added bonus of protecting our instruments from strain.
Bottom line... for master singing try backing off breath pressure. Just a bit, especially on the power notes. It's what I call "pulling" instead of "pushing" for power, a concept I teach in my "Power, Path and Performance"vocal training method.
