An apparatus and method for a note locator for stringed instruments, as well as a method of use, is presented. The application of acoustic laws allows calculation of the location for note position indicators upon the note locator. These locations are presented in a visual format. Note locator (10) comprises a flexible planar top and bottom surface wherein the top surface has note position indicators (60) of color and the bottom surface has an adhesive so that it can be placed beneath the strings of the instrument along the fingerboard without interfering with the normal operation of the instrument. Fingerboard alignment indicators (16, 18) aid in correct placement of the note locator. The user learns correct finger placement for playing the instrument by visually identifying colors with the notes of the equitempered chromatic scale. Diatonic scale note position indicators (32, 36, 38, 42, 46, 50, and 52) are indicated with various distinct colors while other half step note position indicators (30, 34, 40, 44, and 48) are indicated with a color different from that of the diatonic scale note position indicators.

A conically shaped, keyless plastic wind instrument with eight holes, consisting of a single body and a detachable a mouthpiece. The instrument is fully chromatic and capable of playing in any of the traditional twelve keys of Western music-producing notes through a player's vibration of a single reed affixed to a soprano saxophone type mouthpiece, and through the opening or closing of a plurality of tone holes along its length by use of the fingers. The instrument is one of a family of keyless saxophones which can be pitched in the alto, soprano, and soprano range by the lengthening or shortening of the body and by changing the location of the eight finger holes. By opening or closing the finger holes, the standing sound wave-created inside the instrument by the player's vibration of the reed affixed to the mouthpiece-is intersected at locations along the length of the body producing a vibration at a determined musical pitch, the scale of which is tuned to A=440, standard concert tuning. All members of this instrument family have the same fingering patterns, which are based on recorder (or vertical flute) fingerings.

An electronic stringed instrument is provided where the value of a pitch that has been currently detected and the value of a pitch that has been stored are compared.

Method and apparatus in which optical sources deliver light to small specific areas of the cochlea for purposes of stimulation, which brings the advantage of increased spectral fidelity because the stimulation illumination can be more specifically placed than electrical-stimulation signals. In some embodiments, a plurality of light sources or light delivery devices are placed at finely-spaced locations along the cochlea but only a fraction of them are used within any short period of time due to the limitation of power delivery to the optical emitters and a restriction on heat within the cochlea due to the absorption of the optical stimulation signals. The ability to choose which optical sources are used at any given time frame provides the ability to choose the sources that illuminate and thus stimulate the particular small areas of the cochlea that generate nerve signals perceived as the semitone frequencies found in Western music.
