This elegantly carved harp magically never untunes and can magically change size, being small enough to fit in your palm or large as a normal floor harp. It gives advantage on performance checks made while playing it. 

Additionally, while attuned to the harp you can perform a 10 minute ritual to attract and gain the service of woodland creature as a helper. This creature must be of CR 1/2 or lower, it cannot attack, and it retains all its base statistics. 

Notes: Advantage: Performance, Bard
