Please help. My husband has for a long time wanted to play pennywhistle. I thought for Christmas I'd get him lessons but don't know which whistle to buy for him. He's got several Clark ones, I think the C and D. However, they don't seem to have much of a range and, to be honest, they don't sound very good. I know you can get a very long whistle. Is this the Low D one and does it sound better. Thank you for any input you can give.
