- Examine the body of the instrument. If the body is made of wood, then you have a wooden clarinet. If it is made of another material, such as plastic or metal, then you have a plastic or metal clarinet.
- Look at the keywork. The keywork of the clarinet is typically made of metal, and it can vary depending on the manufacturer and model of the clarinet. Some clues that can help you identify your clarinet include the shape of the keys and the arrangement of the keywork.
- Check the stamp or engraving near the barrel of your clarinet. This stamp will typically include the model name, serial number, and manufacturer of your clarinet.
- Measure the length of the clarinet. Clarinets come in different sizes and keys. The most common size is the B-flat clarinet, which measures about 27.5 inches (70 cm) in length.
- Consult with a clarinet teacher or technician. If you are still unsure about what type of clarinet you have, you can ask a clarinet specialist to help you identify it.
