Hi Bzean123!

Also, check that the melodica is airtight. This means that no air is escaping through tiny gaps around the air chamber. You can do this by blowing through the mouthpiece without pressing any keys. If it’s airtight, you won’t be able to blow – your breath will encounter complete resistance. If there is a leak, you’ll be able to blow a small amount of air into the instrument.
