Using the Antigua Vosi AS2155LN Eb Alto Saxophone is easy. First, assemble the saxophone parts carefully. Put the mouthpiece on the neck and attach the neck to the body. Then, place the reed on the mouthpiece and secure it with a ligature. When you play, hold the saxophone in a comfortable position, covering the holes with your fingers as needed. To make a sound, blow gently through the mouthpiece and use your fingers to change notes. For maintenance, after each use, wipe the saxophone with a soft cloth to remove moisture. You can also use a cleaning rod and a swab to clean the inside of the instrument. Keep it in a dry place and away from extreme temperatures. If you're not using it for a long time, remove the reed and store it separately. Be careful when handling the keys to avoid any damage. And don't forget to check the pads regularly for any signs of wear and tear.
