I bought this for my son who became obsessed with steel drum. We've got two pricier ones but both had a full note. I was disappointed. I realized that my son really uses it as a toy. He doesnt really play much music on it. He just likes the sounds. So I went for a cheaper and simpler one. He's happy that it's not super big and heavy and has all the element he was looking for anyway. 11 notes are a bit limited and you cannot play that many songs. But it's enough for just playing for fun.
