Using the Antigua Vosi AS2155LQ Eb Alto Saxophone is quite straightforward. First, assemble the saxophone parts carefully. Attach the mouthpiece to the neck and then connect the neck to the body. Adjust the reed on the mouthpiece so it fits well. When you're ready to play, put your fingers on the keys as you've learned in your lessons. For the best sound, blow steadily into the mouthpiece. As for maintenance, after each use, use a cleaning cloth to dry the inside of the saxophone to prevent moisture damage. Keep the keys clean and lubricated regularly. Store the saxophone in its case when not in use to protect it from scratches and dust. Avoid exposing it to extreme temperatures or humidity. Also, check the pads and resonators from time to time to make sure they're in good condition. If you notice any problems, it's best to have a professional repair it.
