A system and method to help players of string instruments with the usability of their instruments, particularly with the detection and assessment of the mechanical status of their instrument's strings and in determining when and/or whether the strings need to be replaced.

A tuning device for a musical instrument includes a body and a neck extending out from the instrument's body. The neck has a free end including a headstock. The headstock includes an anterior instrument face, a posterior instrument face essentially opposite to the anterior instrument face, and at least one tuning key disposed on the posterior instrument face. The tuning device includes a tuning display and is engagable with one or more of the at least one tuning key, having a shape of a right-handed triangle fused to an oblong. The tuning display is disposed on the hypotenuse of the triangle. The display is positioned on the tuning device such as to essentially face the instrument's body when the tuning device is both engaged with the one or more tuning key, and entirely disposed above the posterior surface.

The present invention provides an acoustic resonator coupling for securing a tuning fork within a stringed instrument body. The acoustic resonator coupling incorporates the use of retractable prong members to imbed the coupling to the wood of the instrument body. The prong members penetrate the wood leaving only a very small prick mark that does not mar the material of the instrument body thus retaining the value and aesthetics of the stringed instrument. Provisions are provided on the acoustic resonator coupling permitting for the releasable mounting of the tuning fork.

The disclosure provides an approach for tuning musical instruments. In one embodiment, a tuning application determines frequencies of a series of notes played on a brass instrument, either with open tuning or with a valve pressed. As a musician holds a last note in the series and a tuning or valve slide is moved, the tuning application determines, based on a change in frequency of the last note and the measured frequencies of the other notes in the series, the change in frequency of the other notes. The tuning application then determines a compromise tuning that minimizes the total difference between the current frequencies of the notes and known note frequencies in a frequency table or previously tuned note frequencies if any of the notes were previously tuned. Upon achieving the compromise tuning, the musician or an actuator is instructed to stop moving the tuning or valve slide.

A pitch information generation device includes a first envelope generator configured to generate, with regard to a first sound range, a first envelope that attenuates at a first rate of change from a detected value corresponding to a peak in the sound signal, a second envelope generator configured to generate, with regard to a second sound range, which includes a sound range of higher frequency than the first sound range, a second envelope that attenuates from a detected value corresponding to a peak in the sound signal at a second rate of change. The second rate of change is greater than the first rate of change. A pitch information identifier is configured to identify the pitch information based on the first envelope and the second envelope.

The foldable bracket includes a leg bracket assembly, a pulling-rod assembly, and a supporting assembly. The pulling-rod assembly has a pulling-rod assembly first end and a pulling-rod assembly second end that are opposite to each other. The leg bracket assembly is coupled to the pulling-rod assembly first end. The supporting assembly is foldably coupled to the pulling-rod assembly second end. The supporting assembly has an unfolded state and a retracted state. The supporting assembly includes at least a main bracket, a first connecting rod assembly, and a second connecting rod assembly. In the unfolded state, the first connecting rod assembly and the second connecting rod assembly are unfolded and form a supporting surface. In the retracted state, the first connecting rod assembly and the second connecting rod assembly are affixed with the main bracket, respectively, and form a rod-shaped structure.

Tuning information is calculated based on input sounds. A tuning estimating apparatus includes an input sound acquirer for acquiring input sounds, a pitch calculator for calculating pitches of the input sounds acquired by the input sound acquirer, and a tuning value calculator for calculating a tuning value representing an offset between a tuning reference position serving as a reference for tuning and a reference position on a first distribution of the pitches calculated by the pitch calculator, based on a peak of the first distribution. The tuning value calculator calculates the tuning value based on the positional relationship of a periodic peak group of the first distribution.
