It's a good thing you have great discipline even though you already know and master your instrument. It seems that long notes may seem tiresome but they are fundamental to achieve a note that hooks everyone. It's like when someone is playing a song we are always attentive to that long note that makes us sigh. Thank you very much for bringing us this video where you explain very well the importance of long notes and the way they are played with your instrument. Very complete all the information about this topic in your video. Wonderful as you played at the end for all of us, congratulations and always enjoy this great musical instrument. Music is happiness and love. May you all have a wonderful day to the rhythm of good music.
