A saxophone has a body tube, a high-F #structure, and a side-Bb structure. The body tube has a high-F #tone hole and a side-Bb hole. The high-F #structure opens or closes the high-F #tone hole. The side-Bb structure has a side-Bb tone-hole cover, a side-Bb driving assembly, an auxiliary key, and a main key. The main key is separated from the auxiliary key. The auxiliary key is disposed above a high F #key of the high-F #structure along a vertical line. The auxiliary key and the main key are separately arranged around a centerline of the body tube. The auxiliary key and the main key correspond in height position. Both of the auxiliary key and the main key are connected to the side-Bb driving assembly and drive the side-Bb tone-hole cover to close or open the side-Bb tone hole.

A headphone ear cup holds the transducer. This patent focuses on applying tone wood porting theory to the headphone cup. Simply put, tone wood theory states that certain woods provide a tonality to the music. The practice of speaker porting has been in use for many years to extend the bass response of a speaker. By combining tone woods with porting, a more musical presentation created than by using a polymer or metal cup.

Systems for raising pads on musical instruments to enable drying of pads and increase air flow around the pad and a body of the musical instrument. A vent spanner device, including a positioning feature and a retention feature, is placed between a pad and its corresponding vent to create an air gap. A pad prop is placed against a key mechanism or between the key mechanism and/or the body to raise a pad from sealing its corresponding vent. A linkage feature connects one or more vent spanners, pad props, end pieces, key mechanisms, or the body, and provides storage.

Air pressure regulation devices and methods of using air pressure regulation devices are provided to adjustably control air flow to a bagpipe chanter reed. An air pressure regulation device can include a main body, a valve rotatably attached to the main body, and a cap attached to the main body. The valve may be rotatably adjustable to control an amount of air that flows through the air pressure regulation device. Methods of using an air pressure regulation device may include installing an air pressure regulation device on a bagpipe, adjusting the air pressure regulation device, and playing the bagpipe.
