Abstract: Performance information of one or more accompaniment parts is extracted from original performance information. Arranged accompaniment performance information is created using, in accordance with a predetermined arranging condition, only any one or more of pitch names included in the extracted accompaniment performance information. The predetermined arranging condition comprises instructing that any of chord component notes be thinned out in an identified chord progression, and arranged accompaniment performance information is created by thinning out an accompaniment note of a pitch name corresponding to the chord component note having been instructed to be thinned out.

Abstract: Systems and methods capable of providing adaptive and responsive accompaniment to music with fixed chord progressions, such as jazz and pop, are provided. A system can include one or more sound-capturing devices, a signal analyzer to analyze captured sound signals, and an electronic sound-producing component that produces electronic sounds as an accompaniment.

Abstract: A tool for teaching the playing of a musical instrument includes a control and a signaling unit that instruct a student as to the proper time to strike an instrument. The control is configured to provide a series of signals, through the signaling unit, that denote a tempo for music or a beat, a warning that the time to strike the instrument is approaching, and a signal when it is time to strike the instrument in accordance with the beat or music.

Abstract: A musical instrument is comprised of a keyboard, a strummer, and a processor. The keyboard and strummer send event messages to the processor whenever a key is pressed, or a string is plucked, respectively. At the time a string is plucked, the processor dynamically assigns a note to the string, based on which keys are depressed. The dynamic note assignment ensures that the top, or a predefined string is part of any selected chord or scale passage. In response to strummer and keyboard events, the processor selects different timbres or articulations of the note including: clean, thumb harmonics, muted, hammer-on, or pull-off. The processor plays back recorded samples or synthesized tones to emulate the sounds of different playing techniques on an acoustic, electric, bass guitar or other stringed instruments.

Abstract: Disclosed is an apparatus and method for outputting horn sounds using a touch pattern. The apparatus includes: a storage unit configured to store horn sounds matched to various touch patterns; a touch detection unit equipped in a steering wheel of a vehicle configured to detect a driver's touch; a touch pattern recognition unit configured to recognize a driver's touch pattern detected by the touch detection unit; a controller configured to identify a horn sound corresponding to the touch pattern recognized by the touch pattern recognition unit from the storage unit, and to send it to a horn output unit; which allows a user to control what sounds are output by the horn using nothing more than simple touch gestures. Additionally, the apparatus and method enable a user to produce different horn outputs to correspond to different situations.

Abstract: A user is asked to perform tapping at beat positions by using a tapping detection section while listening to the beginning of a waveform from which beats are to be detected. When a fluctuation calculation section determines that tapping fluctuation falls in a predetermined range, a beat interval close in number to the tempo of the tapping is selected from among beat-interval candidates detected by a tempo-candidate detection section, and a tapping position where tapping becomes stable is determined to be the starting beat position. Tapping by the user for just some beats allows beats to be detected in the entire musical piece more correctly.

Abstract: A rhythmic tone generator includes a casing that houses a rhythm signal generating circuit, a battery and a tone generating device, and that is positioned and held on the concha by an attaching device, so that the rhythmic tone generator is attached to the ear without being inserted into the ear hole, and operates to generate rhythmic tones right in the vicinity of the ear hole. On the rear surface of the casing are disposed a display device connected to the rhythmic tone generating circuit and operable to display a parameter representing the speed of the rhythm signal, and a push-button switch that may be operated with a hand while the tone generator is being attached to the ear.

Abstract: A musical toy in which tappers on the ends of swinging bodies can be swung up and kept upswung without using any springs; space for spring mounting is thereby made unnecessary and the toy can be made small; the manufacturing process can be simplified and resulting mass production benefits and cost reductions can be achieved, and which can operate stably over a long period of time. There are provided a toy body 7, a sound producing body 5 and a control device 54, and the toy body 7 comprises first permanent magnets 23a and 23b and swinging bodies 9a and 9b mounted in the vicinity of the first permanent magnets 23a and 23b.

Abstract: A technique for recording a performance of a musical work having a persistent, accented beat in which substituted for this beat are synthesized sound effects simulating those associated with arcade electronic games in a percussive format. Hence when the recording is played back, the listener receives an acoustical image in which the music is heard in an arcade-like environment. To produce this recording, a system is provided in which characteristic arcade game sound effects are simulated in a music synthesizer for audio duplication and are reduced to a single keystroke, thereby enabling an operator to generate a percussive audio pulse which is mixed in a recording with the other components of the performed work. When the recording is played back, it incorporates these arcade game sound-effects pulses which define the accented beat of the music.
