Whether you are a professional pianos player, or you play just to keep yourself busy and entertained, you need to be careful how you handle pianos. This will determine how long they will last and the quality of music that they will be playing. Servicing your piano every few months is compulsory.
Ask a professional to come into your house to ensure that everything in your piano is in top working condition. Also, learn a few basic things about the workings of a piano so that you can do weekly maintenance on your own, like tuning of the internal knobs.
This knowledge will also help you to know if something is amiss on your piano, its severity and if you can fix it yourself. However, depending on how bad your piano is broken, do not attempt to repair it yourself in case you make matters worse. Also do occasional dusting inside the piano to keep it working well.
