Abstract: A system for teaching music theory. The system includes a music theory teaching methodology worksheet having: a starting section; a note teaching section; and a circle of fifths chart. Each of the starting section, the note teaching section, and the circle of fifths chart comprise fillable fields that are fillable by a user of the worksheet.

Abstract: An arpeggiation controller musical instrument operable to receive a user hand gesture and play an arpeggiation pattern. The musical instrument includes an X-Y pad operable to detect the user hand gesture. The user hand gesture sets one or more parameters of the arpeggiation pattern. The musical instrument also includes an arpeggiation generator operable to create the arpeggiation pattern based on the user hand gesture.

Abstract: A musical instrument operable to play a multi-component percussive beat. The musical instrument includes a plurality of finger controllers, wherein each finger controller is operable to control a component part of the multi-component percussive beat. Each of the plurality of finger controllers has a touch-sensitive range providing a plurality of actuation regions, and each actuation region is operable to play a hit pattern associated with a component percussion track representing a respective component of the multi-component percussive beat.

Abstract: A musical instrument including a note player operable to produce individual notes in a selected key, wherein a layout of the note player corresponds to a selected chord, in which three finger regions of the note player correspond to a root note, a third note, and a fifth note of the selected chord in the selected key.

Abstract: A musical instrument, including a chord player section having at least one chord player operable to play a selected chord, the at least one chord player including a finger-actuatable first pad having a first center point function and a plurality of first perimeter point functions. The first center point function and the plurality of first perimeter point functions are respectively operable to generate a primary chord having a chord root note or variations of the primary chord having the chord root note.

Abstract: An airflow cooling lid for hot beverage containers enables the user to cool down the beverage in the container by blowing outside air across the surface of the beverage without removal of the lid. The airflow cooling lid includes a circular cover snuggly placed over a hot beverage container having a mounting rim, a surface portion, a sipping portal in form of an opening for consuming the beverage, an airflow opening to be used as either the intake or exhaust portal for the air drawn over the surface of the beverage, and a pinhole vent opening for allowing outside air into the container and pressure release in the event both portals are plugged. The airflow portal is angled outward to allow the exhaust air to flow away from the face when blowing through either portal.

Abstract: In the field of lids for beverage containers, an airflow cooling lid for hot beverage containers that enables the user to cool down the beverage in the container by blowing outside air across the surface of the beverage without removal of the lid. The airflow cooling lid comprises a circular cover snuggly placed over a hot beverage container having a mounting rim, a surface portion, a drinking opening in form of an opening for consuming the beverage and an exhaust opening to be used as either the intake or exhaust portal for the air drawn over the surface of the beverage. Either or both the drinking opening or the exhaust opening may be angled outward to allow the exhaust air to flow away from the face when blowing through either portal.
