This one is really silly. I tune it a whole octave above a standard soprano ukulele – gCEA. It’s basically impossible to play complicated chords on, because the strings are so close together, but tunes are do-able, and it can sound great if you try faster strumming on it with simple bar chords. I think it was designed as an ornament or perhaps a fridge magnet, but it has a great, unique, and tiny sound.
