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.

Various implementations directed to price time priority queue for virtual power plant and connected grid aggregation are provided. In one implementation, a method may include receiving origin location data and destination location data. The method may also include generating nodal power networks based on the optimized origin location data and the destination location data. The method may further include determining virtual power plant hubs along the transmission route and network, where the virtual hubs include a first virtual hub based on the origin location data and a second virtual hub based on the destination location data. The method may additionally include receiving power device data for the geolocation exchange units. In addition, the method may include receiving market depth data for a geolocation exchange for the geolocation exchange units based on the virtual power plant nodal sequences.

The method may additionally include receiving IoT device data for the geolocation exchange units. In addition, the method may include receiving market depth data for a geolocation exchange for the geolocation exchange units based on the multi-dimension map tile repository nodal sequences.

A method of explicit note-location for stringed instruments synthesizing tablature notation and traditional classical staff notation for more fluid sight-reading of musical pieces. The invention makes explicit the note-locations-on-stringed-instruments of notated pitches. The method including the steps of marking a musical note or musical notes representing a particular pitch on the five-lined music staff or other form of graphic music notation system being used for said stringed instrument, marking a first numerical indicator on the musical note that indicates the location, along a string, on the stringed instrument, at which the at least one musical note is intended to be sounded from, and marking a second numerical indicator on the at least one musical note, appended to the first numerical indicator, that indicates which specific string of the stringed instrument on which the at least one musical note is intended to be sounded. Each first and second numerical indicator being marked together as a single, composite numerical indicator upon said musical note.

The present disclosure provides a methodology and toolkit for music literacy learning, comprising a plurality of tools for developing, practicing and understanding the elements, functions and dynamics of music reading, composing, listening, critiquing and ensemble performing skills. The kit comprises: a receptacle configured to represent a music note or rhythm, the receptacle comprising a slot; and a modifier card configured to be inserted into the slot of the receptacle for modifying an accent, volume, articulation, or chromatic alteration of the music note or rhythm based on a design of the modifier card, wherein the receptacle and modifier card serves as an indication for a user to vocally perform the modified music note or rhythm. Other kits detailed in this application contain charts, repertoire matrixbooks, and practice instruments that include detailed instructions as to how preschool children music literacy skills and how these skills can be transferred to the invented silent practice musical instruments that finally lead to reading, performing and composition with standard notation and performance on conventional music musical instruments.

An information processing system includes an image obtaining circuit and a display control circuit. The image obtaining circuit is configured to obtain observation images of a first keyboard of a first keyboard instrument. The display control circuit is configured to display, on a display device, the observation images and reference images. The reference images include moving images of at least one hand and one or more fingers of a reference performer who is playing a second keyboard of a second keyboard instrument. The at least one hand and the one or more fingers of the reference performer are displayed overlapping the first keyboard included in the observation images.
