Well done! You have found the cello!
The cello is a large member of the string family.
Raised off the ground on a tail spike, the cello rests against the knee of a seated player. The cello can be plucked or bowed.
The body of the cello is made of hollow wood. The famous string instrument maker Antonio Stradivari set the standard for the size of a cello, still used by instrument makers today.
