<p>The invention relates to devices for producing sound, in particular to musical instruments having a fixed pitch such as a piano and guitar. The tone row of the inventive musical instrument having a fixed pitch and an even-tempered tone row comprises 22 steps and the ratio between a tuning frequency of any one of them and the tuning frequency of an adjacent step, which is lower along the tone row, is equal to 221/22. The tuning error of any step is equal to or less than 6 cents.</p> |
