I played trumpet for many years and at a high level in college. I hope this helps but for me I became a much better player when I realized some of my insecurities translated through the horn. What helped was understanding that the love and passion of making art through my instrument is a lot greater than being scared of making a mistake or being rejected because of not being good enough. The truth is we all have gifts and it’s our duty to give them life, not only for you but for others to enjoy. And PRACTICE PRACTICE PRACTICE you got this !!
