<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Ahhhh the clavichord.... probably THEE most under-rated and underdeveloped music instrument idea of our time. The keys have this little capstan like nail... thumbtackish like thing.... where the capstan usually is.. more or less. When you press down the key this hits the string and stays there until you let the key down. Makes a really neat sound and double serves to determine the pitch of the note... sort of like left hand hammering a guitar... but neater. A square grand on the other hand is a piano family instrument..  hammers that have an escape mechanism. Clavichords are by and large also a bit smaller then square grands...tho there are some pretty big clavichords. If it was a Clavichord... it would be interesting to hear how you tuned it :) Cheers RicB Alpha88x@aol.com wrote: <blockquote TYPE=CITE>Greetings,             What is the difference between a square grand and a clavichord? I went to tune my first one and the customer called it a square grand, however to me, it looked like a late clavichord. rookie, Julia Gottchall, Reading PA</blockquote> </html>
