Little does Octavia know, but her surprise birthday gift from her Grandmother is a grand piano; but this piano is much more than it seems.

Fortepiano, for that is what her piano is called, is very much a person in his own right. Little does our friendly piano realise, but he has lodgers under his strings. They are called the Triplets; Poco, Pochettino, (Poch for short), and Placido, all three very mischievous little people.

This story is all about how the Triplets cause a lot of trouble for not only Fortepiano and Octavia, but also Octavia’s music teacher, Mrs. Lines.
