This one is mainly a question for high brass but if any other could help me that would be great. I'm in 11th grade and I am a 3rd year trumpet. Right now, we are focusing on marching songs, but after Football season, we mainly play concert songs. One of those is a pretty well known trumpet piece called "A Trumpeter's Lullaby". I normally am a second chair but my band director "surprised me" and gave me solo. I've played it before but never solo. Since I am doing the solo, should I use vibrato at the appropriate times? If so, what method should I use? I obviously wouldn't use the wind speed method. So I would either use my hand or move my jaw slightly. Which one should I use? Let me know!
