There are many things we should not forget while we blow into our fine instruments if we do not want the resulting sounds to be lost in banality or oblivion.
I have a very simple suggestion for you. Sit down somewhere comfortable in your own house, relax and concentrate. Put the Kyrie of the B minor Mass (there is no brass in this movement, so you will not be distracted). Its message is clear and forthright: progress, faith and hope come together in the transcendent universe of music. Let us try to follow it. (Do not hesitate to listen to it again, three times, as many times as necessary!)
