In an embodiment a flute head joint includes a beak-shaped mouthpiece and a curved neck, wherein the mouthpiece comprises a curved labium, and wherein a chamber of the mouthpiece has a larger diameter than an inner cavity of the neck.

A non-transitory computer-readable recording medium storing a program that causes a computer to execute a process for evaluating a voice, the process includes analyzing a voice signal to detect a pitch frequency; selecting an evaluation target region to be evaluated in the detected pitch frequency based on a distribution of a detection rate of the detected pitch frequency; and evaluating a voice based on the distribution of the detection rate and the selected evaluation target region. An Impression of the voice using a correction to the distribution is evaluated and determined as good when a spread of the corrected distribution is larger than or equal to a certain threshold.

A children's toy with capacitive touch interactivity. The children's toy generally includes a user input overlay panel and one or more capacitive touch sensors. The overlay panel may be formed from a capacitive touch conductive natural organic material such as wood. The toy can be shaped and ornamented to resemble a musical instrument, and configured to play music in response to user input applied to the user input overlay panel and sensed by the capacitive touch sensors.

Playback, recording, and analysis of music scales via software configuration. In an embodiment, a graphical user interface is generated with staff and keyboard canvases, visually representing a music staff and keyboard, respectively, a scale input, parameter input(s), and a play input. In response to selection of a scale, the staff canvas is updated to visually represent the notes in the scale. In response to the selection of a musical parameter, the staff canvas and/or keyboard canvas are updated to reflect the musical parameter. In response to selection of the play input, a soundtrack of the scale is output, while simultaneously highlighting the note, being played, on the staff canvas and the key, associated with the note being played, on the keyboard canvas.

An instructional method of an electronic keyboard includes: obtaining a playing script, wherein the playing script is generated by a first terminal or a cloud server according to a first signal generated by a recording electronic keyboard and a time point of receiving the first signal, and the playing script is configured to indicate a corresponding relationship between to-be-pressed first keys and time points of pressing the to-be-pressed first keys; and controlling indicator lights on the first keys of the instructional electronic keyboard to be turned on or off according to the playing script. In this way, a user can be prompted to press the keys through the indicator lights on the electronic keyboard, which aids the user in learning how to play the electronic keyboard.
