For as long as I can remember almost all my reed have had the fate where once opened from the package and prepared they sounds stunning but then in a few minutes they become blocked in the inside and become very hard to play to the point where some notes are not playable. Before I play I always brush,rinse my mouth and drink only water. Has anyone ever had this situation happen to them? Its becoming very frustrating because I know I can create a better tone than what I hear majority of the time and its discouraging me to keep playing the alto sax. I currently play with Vandoren Java 3 but its happened to every strength and brand of reed I have played. I will greatly appreciate the help!
