Using this accordion is straightforward. Hold it comfortably with the straps around your shoulders. Press the keys on the treble side to play melodies and use the bass buttons on the other side for accompaniment. When not in use, keep it in the provided hardshell case to protect it from damage. Clean it gently with a soft, dry cloth to remove dust. Avoid exposing it to extreme temperatures and humidity as this can affect the reeds and the wood. If you need to tune it, it's best to consult a professional accordion technician.
