Make sure you are not playing so loud that you are blowing the worship out of the room.
HAHAHAHAHAHAHAHAHAHAAAAAAAAAAAAAAAAAAAA
AAAAA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Whew!!
Man, that's rich. I have noticed that the guys who usually play loudest aren't really all that good. It's just funny that you should mention that. I have a 50 year old sax student and that was one of the first things I had to teach him, come down in volume. . . control your tone. . .
All of these are good common sense musical points. This one just stuck out to me the most.
One thing to add. I like what Wolfram said about playing the melody. Many times playing the melody with grace notes added here and there is much more effective and meaningful than just running scales fast. If you can, have your dad listen to Donald Hayes. He's a master at this. And he's prominent in the Gospel arena. He can be heard on the following projects:
John P. Kee -- Reunion, Not Guilty, ColorBlind
Colorado Mass Choir (1st 3 CDs)
Quiet Times
Reflections
Fred Hammond -- Pages of Life
Kirk Franklin -- Christmas
Ben Tankard -- Instrumentally Yours
James Moore -- Live at Jackson State University
You can google him and more items on his discography may pop up. Don't try to make your dad play like him, but he's a good example of how to be musically aware.
