Dear Manny, I have always played with very little vibrato as I always liked a very pure straight sound. When I use vibrato to colour/warm the tone I use a slight vertical movement of my trumpet to regulate it, as for me I find this easier, and it sounds more musical than using my lips, which are very used to plying with no vibrato. However, I know that many players do not use this technique and use their lips. When I am teaching my students some naturally have a lovely vibrato, but for those that don't who need to develop this skill, which method do you think is best to teach to them? I have been encouraging them to try both ways to see which works/sounds best for them and then go with that, but is one method better in your opinion than the other, and how would you approach teaching students how to play with vibrato? Best regards, Graham.
