Duets.
It seems logical today for me to talk about duets because I have been playing one with mini witch on our flutes. Magick with others is very like music. As within a rehearsal or piece of music you have to decide whether the mistake requires stopping and beginning again or carrying on.

 It matters little who made the mistakes, though it is fine to feel pleased when you didn't make any. It doesn't make you superior to the other player for we all miss notes sometimes, get our tuning off or just have a bad day. Be gracious and kind when you play with others and allow them their space as well as their mistakes. It is how we learn. Keep your music tidy, and your instruments clean. It is not only sensible but respectful to those objects and also to the music. Practice makes better, but never perfect. A spine tingling performance need not be note perfect and some that are, seem flat and dull. While some seem to torture The Art in the name of money, remember that it is okay to earn money doing what you love.
Music build bridges, sheds hope and light where there was despair. It can reveal and hide the truest things about the performer and what it means to be human and can touch on the Divine. It can happen anywhere. When it happen spontaneously it is one of the most memorable and wonderful experiences in the world.
