Patent number: 5929358Abstract: Methods and apparatus determine tuning frequencies for an instrument, such as a piano, by sounding at least three musical notes of the instrument. The sounded notes are recorded and digitally filtered to generate directly partial ladders representative of the sounded notes. The partial ladders are equalized with respective to a reference frequency or one another to determine tuning frequencies for the sounded notes. Tuning frequencies for the remaining notes of the instrument are then determined from the equalized partial ladders. Tone generators which produce the musical notes, such as strings on a piano, are then adjusted to conform the musical notes which they generate to the tuning frequencies. Preferably, the tone generators are adjusted using a display which provides highly accurate macro and micro tuning information in a single display by graphically and dynamically displaying pitch differences of the musical notes generated by the tone generators relative to pitches of the tuning frequencies.Type: GrantFiled: June 4, 1997Date of Patent: July 27, 1999Assignee: Reyburn Piano Service, Inc.Inventor: Dean Laurence Reyburn
