An environmentally-regulated portable musical instrument case is provided which can insulate the musical instrument from external temperature and humidity changes. The case has an internal cavity designed to hold the musical instrument. The walls of the cavity are designed to reduce thermal transfer between the internal cavity and the surrounding environment. A temperature regulating apparatus actively or passively further controls the temperature of the internal cavity while a humidity control device controls the humidity.

A storage case for musical accessories includes a bottom wall; an outer sidewall extending from the bottom wall, the outer sidewall and bottom wall defining an interior space; a divider wall extending from the bottom wall between a first location on the outer sidewall and a second location on the outer sidewall, the divider wall configured to divide the interior space into a first compartment and a second compartment; a first lid hingedly attached to the first compartment and configured to enclose the first compartment; and a second lid hingedly attached to the second compartment and configured to enclose the second compartment.

In a musical performance support system including a sensor device that is attached to a musical instrument and an operation device that is able to perform wireless communication mutually with the sensor device and is able to perform communication with an instructor terminal of an instructor via a server, the sensor device transmits a detection signal detected by an acceleration sensor that has at least to detection axes to the operation device, the operation device generates practice result information of musical performance of a user using the musical instrument and transmits the practice result information to the server, and the operation device receives guidance information in response to the practice result information from the instructor terminal through the server and causes display means to display the guidance information.

A machine that attaches to any piano and pushes its keys and foot pedals in the order of any song. The machine can download songs from a software program and record songs played manually on a piano to replay them.

A device has a plurality of different mouthpieces that can be mounted on an elongate body. Each mounted mouthpiece is spaced from the central axis of the elongate body. In order to introduce different embouchures, a music student can blow into successive ones of the plurality of different mouthpieces. The student can hold the elongate body when using the device.

An article for retaining an object against a musical instrument including a mat of a material that extends from a first surface to a second surface. The first surface contacts a contoured surface of the musical instrument and the second surface contacting the object. The mat flexes to match the contoured surface of the musical instrument. The static coefficient of friction of the first surface is greater than the static coefficient of friction of the contoured surface of the musical instrument. As a result, the mat removably retains the object on the contoured surface of the musical instrument.

A speaker includes a first flat diaphragm, an actuator that applies vibration corresponding to a sound signal to the first flat diaphragm, and a second flat diaphragm separated from the first flat diaphragm and vibrated by the actuator.

A stencil device and associated method of use for drawing, painting, etching, or otherwise marking multiple parallel lines are disclosed. The stencil may include two or more slots for drawing parallel lines, with even spacing between the lines. The stencil may also include multiple groupings of multiple slots. The stencil may be used for drawing a single musical staff, or may be configured so as to enable easy and repeatable marking of multiple musical staves. The slots may have varying widths and shapes, such as including curves, to allow for maintaining a substantially straight line even if the material of the stencil flexes or deforms during use. Various widths of slots may also be used to accommodate different marking instruments and dip diameters of different instruments.
