Can you name the book this is from: Laws that govern the frequencies of these musical sounds: 1) The pitch of a musical sound varies as the number of vibrations per second. 2) The pitch of any given string varies inversely as the length of the string -- the shorter the string, the higher the pitch. 3) The pitch of a given musical string varies as the square root of its tension. That is to say, that if a string is stretched with a tension exerted by a weight of ten pounds, it will yield the octave above its original pitch when the weight is increased to four hundred pounds. 4) The pitch of a given musical string varies inversely as it thickness. The thicker the string, the lower the pitch. 5) The pitch of a given musical string varies inversely as the square root of its density. Thus a string of which the density is four times that of another will have one-half the frequency of, and one octave lower pitch than the second string. HINT: The book is from the previous century. -- Duaine Hechler Piano, Player Piano, Pump Organ Tuning, Servicing& Rebuilding Reed Organ Society Member Florissant, MO 63034 (314) 838-5587 dahechler at att.net www.hechlerpianoandorgan.com -- Home& Business user of Linux - 11 years
