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. A determination is made as to whether or not the pitch has dropped roughly a half tone. In those cases where the currently detected pitch has dropped roughly a half tone from the pitch detected a specified period earlier, a tone generator begins the attenuation of a musical tone that is generated and the note height of the musical tone is controlled so that the note height does not change.

A phonetics having vowel phonetic symbols separated into full sound symbols and half sound symbols, and consonant phonetic symbols. The full sounds symbols are represented by letters in the English phonetic symbol. The half sound symbols are represented by simple symbols. The phonetics is suitable for the traditional method of marking pronunciation in dictionaries and also suitable for directly marking the pronunciation on an actual word appearing in books, such that the phonetics can be promoted to be used in English teaching materials, enhancing learning effectiveness of learners.

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.

An adjustable chromatic harmonica incorporating an adjustable mouthpiece where, for each mouth-hole, the player's breath may be selectively connected to one or more available reed cells. This is by means of a rotatable cup-shaped valve, with an opening or port in its side, being mounted in each mouth-hole such that the port can be registered by rotation with one of a group of surrounding air ducts, each of which is connected to one or more reed cells in the body of the harmonica. In some embodiments an apertured slide is interposed between the mouthpiece and the body. In some embodiments devices are provided for rotating the valves in independent groups while the harmonica is being played. In embodiments where each group of mouth-holes can be independently adjusted, a large number of physical states is possible. Consequently, some embodiments have the capability of playing chromatic melodies and several common chord types in all twelve musical keys.

The inventors disclose a new apparatus and method for visual and audible demonstration of musical concepts such as intervals, the tonic, transposition, scales, modes, and chords. The apparatus is based on a primary layer of indicia for each of the 12 chromatic notes of the musical octave, each indicium paired with a touch sensor. A novel means for superimposing additional layers of musical information employs a tonic indicator and encoder, and modular physical indicator pieces or multi-colored LED lights.

The present invention relates to a method for guiding a user in interaction with an insulin pump comprising providing in response to a user interaction at least one of (i) a first acoustic signal comprising at least five descending halftones, wherein the duration of each tone is independently selected from a range of from 0.025 s to 5 s; (ii) a second acoustic signal comprising at least five ascending halftones, wherein the duration of each tone is independently selected from a range of from 0.025 s to 5 s; (iii) a third acoustic signal comprising at least seven ascending halftones, wherein the duration of each tone is independently selected from a range of from 0.025 s to 5 s; (iv) a fourth acoustic signal comprising at least two alternating tritones, wherein the duration of each tone is independently selected from a range of from 0.025 s to 5 s; (v) a fifth acoustic signal of four tones with a duration of from 0.025 s to 0.5 s, followed by a single tone with a duration of at least twofold of any one of the preceding four tones, wherein at least one tone of the acoustic signals of (i) to (v) has a frequency in the range of from 1500 Hz to 4000 Hz, in an embodiment of from 1700 Hz to 3800 Hz. Further, the present invention relates to devices, computer program products, and uses related thereto.

The invention relates to a suspended sound transposition chorded instrument which is manufactured by a modern manufacturing process technology. The suspended sound transposition chorded instrument comprises a chorded instrument framework and an independent sound box suspended and supported on the chorded instrument framework; the right end of a chord is coiled on a chord shaft nail through a right chord pillow wheel and a tensioning wheel; the chorded instrument is characterized in that: each chord is provided with a group of toning and transposition mechanism; the transposition mechanism comprises an upper lever, a pull rod, a lower lever, a supporting wheel arranged in the lower lever, and a fixed chord tone sheet and a semitone cam sheet which are matched with the supporting wheel and arranged on a hexagonal transposition spindle; the rotating pivot of the upper lever is the right chord pillow wheel; and the rotating pivot of the lower lever is a movable sliding support. In the suspended sound transposition chorded instrument, the upper lever and the lower lever are linked to the toning and transposition mechanism, a semitone variable can be adjusted under the condition of not changing the fixed chord tone. The suspended sound transposition chorded instrument has the characteristics that: the generation efficiency is high, mega bass having high penetrating capability can bemade, a five-sound twelve-tone transposition function can be realized, and the chorded instrument is convenient and quick, and precise in tone; moreover, in the twelve transposition tones, each chordonly changes semitone, so the elasticity of the chord can be protected fully.

Example embodiments relate to techniques for training an artificial neural network or other machine learning encoder to accurately predict the pitch of input audio samples in a pitch space that is semitone or otherwise logarithmic scaled. An example method may include generating two training samples from a sample of audio training data by applying two different pitch shifts to the sample of audio training data. This may be accomplished by converting samples of the audio data to the frequency domain and then shifting the converted data. These known displacements are then compared to predicted pitches generated by applying the two training samples to the encoder. The encoder is then updated based on the comparison such that the relative pitch output by the encoder is improved in accuracy. The relative pitch values generated by the trained encoder may then be calibrated using one or more audio samples tagged with absolute pitch values.
