This is really strange so just hear me out. I've played sax for around 4 years and i guess I've been doing this for the whole time or its gotten worse maybe. Well basically i tongue with my lip. Its stretched out very far and i tap my bottom lip with the tongue and it allows me to articulate very fast. I hadn't realized it until recently playing Haitian Fight Song which requires very fast tonguing. I really can't stop it now because of how stretched my lower lip is and i actually like how it sounds. It has a nice mellow tone and like i mentioned before i can articulate very well. Is there a word for what this technique is and should i really try to stop?
