Definitions

This invention relates to the field of musical instruments, and more particularly the part thereof relating to electronic keyboard instruments known also as Keyboards, in which a complete octave comprises seven white keys and five black keys, as in a piano.
an electronic keyboard instrument comprising between 46 and 160 keys in which the size of the keys (both white and black) and their travel when depressed are appreciably less than that of those currently in use which, as mentioned, correspond to those of a piano.
the subject matter of this invention in fact comprises an electronic keyboard instrument according to the present state of the art as described in the precharacterizing clause of appended Claim 1, but characterized by the characterizing part of the said claim.
this shows an embodiment of the instrument according to the invention comprising 86 keys and in which, as mentioned, the white keys 2 and black keys 3 are of smaller size than those currently used.
Figure 4 shows the keys forming two consecutive octaves; as a result of the smaller size of the keys it is easy for a musician having good technical training to use intervals of an "eleventh", that is to cover a range comprising 11 notes with the hand, that is e.g. those lying between DO 15 in the first octave and FA 16 in the second octave.
a sensor 7 of a known type which controls the "dynamics" of a key's sound, correcting its duration and/or intensity according to the length of the distance travelled when the key is struck and/or the speed with which it is struck, is attached to every key from LA in the second lower octave 9 ( Figure 7) to DO in seventh octave 10.
Figures 2 and 3 show a sensor fitted centrally beneath a key, but other types of sensors, including those of the known spring type, in which the spring/sensor unit is connected to one end of the corresponding key may also be used. (An arrangement not shown in the figures).
