Hi Greg thanks for your reply. I play sometimes golf in holidays in the US. But it is too little to really progress. In Switzerland you must be a member and that costs a fortune. So I hope to progress on he trumpet. I have another question, the short time now that I practice I noticed that somedays I cannot even produce tones half so clean as the day before. Is that a beginner issue or maybe I play too long? I really love doing it and practice several hours a day if I got the time. And over the change of the years I have a lot of time. Should I better play shorter?

Thanks for your reply
