My middle school director taught me to use the ring finger in the trumpet ring way of holding the trumpet or i guess it could be called the most common way to do it. Anyways i began holding my horn with no fingers in the ring, one finger on top of the 3rd valve slide and three below it and touching the valve casing. I do it exactly the way maynard does it in this picture
My director gets tries to get me to stop. Is this a bad way to hold the horn or is it all personal preference?
