1- If possible, try to arrive a little early. If you are coming by car try to get there in advance so you do not have to spend much time parking and go for coffee. All this to gain some peace of mind and direct your focus to the class.
If you arrive constantly late, you will notice that the first 20, 30 minutes of class are lost. This is mainly because your not calm.
I have many students who confess that the class should be two hours. The first to warm up and the second to play.
2 – Mobile phone in the “AIRPLANE MODE” during the lesson. What income do you expect from the class if you are always on your mobile phone notifications?!
3- Pre-Heating- If possible to play a little earlier. Good for the mobility of the fingers and direct our spirit to the class.
