A Jankó keyboard. The Jankó keyboard is a musical keyboard layout for a piano designed by Paul von Jankó, a Hungarian pianist and engineer, in 1882.It was designed to overcome two limitations on the traditional piano keyboard: the large-scale geometry of the keys (stretching beyond a ninth, or even an octave, can be difficult or impossible for pianists with small hands), and the fact that ...
After Cristofori invented the pianoforte from the harpsichord in 1700, and after it became popular in the decades after 1740, eventually replacing the harpsichord, the piano technique developed tremendously (it was parallel with the piano builders´ progress and piano pedagogy, and as part of it piano fingering changed).
The fingering system he devised has also been adapted to other instruments, such as the oboe and the clarinet. [2] He inspired Hyacinthe Klosé, the inventor of the modern clarinet fingering system. Klosé invented a system for the clarinet that today is the standard nearly worldwide (except Austria, Germany and others).
The pattern of whole and half steps characteristic of a major scale. The intervals from the tonic (keynote) in an upward direction to the second, to the third, to the sixth, and to the seventh scale degrees of a major scale are called major. [1] A major scale is a diatonic scale. The sequence of intervals between the notes of a major scale is:
Piano actions are complex mechanical devices which impose very specific design requirements, virtually all of which were met by Cristofori's action. First, a piano action must be arranged so that a key press does not actually lift the hammer all the way to the string. If it did, the hammer would block on the string and damp its vibrations.
For instance, in a chromatic scale each scale step represents a semitone interval, while a major scale is defined by the interval pattern W–W–H–W–W–W–H, where W stands for whole step (an interval spanning two semitones, e.g. from C to D), and H stands for half-step (e.g. from C to D ♭).
