A drumhead tuning rim system and method for securing and tuning a drumhead on a drum shell of a drum, comprising a drumhead tuning rim apparatus comprising a cable tension dial assembly configured for operably engaging a rim of the drum so as to increase or decrease tension on the rim, the rim being configured for seating over the drumhead on the drum shell, and an apparatus controller configured for operably interfacing with the drumhead tuning rim apparatus so as to selectively control the cable tension dial assembly and thereby adjust the overall pitch of the drumhead as by adjusting the tension on the rim.

A method for assisting a user in tuning a drum comprising the steps of: considering a strike on the drum whereby the strike is detected in a sensor signal in at least one of following domains: a time domain, a frequency domain, a complex domain; recording a first sound fragment of the strike; converting the first sound fragment from the time domain to the frequency domain; analyzing the first sound fragment in order to detect a fundamental tone with fundamental tone frequency of the drum; calculating an overtone frequency or overtone frequency range of a first overtone of the drum by means of a predetermined algorithm related to the fundamental tone frequency; setting a filter with a pass frequency band covering the calculated overtone frequency or overtone frequency range; and indicating, via a user interface, at each further strike when the frequency of the first overtone detected in the pass frequency band is higher or lower than a target overtone frequency.

A novel drum speed key tool that provides improved balance and efficiency for the installation, tightening, and removal of drum lug nuts. The drum speed key tool provides a finger receiving cup to allow a user to insert a finger or grip with their hand and efficiently apply rotational force to the drum speed key while maintaining attached to the drum lug nut with reduced slippage of the drum speed key tool from both the user's grip and the drum lug nut.

A tuning system enabled to be installed inside a drum percussion musical instrument is provided comprising a cylindrical drum shell having a batter head at a top, a bottom, and one or more internal tuning assemblies (ITAs) installed within an inner volume of the drum shell. Sound elements created by striking the batter head of the drum includes any one or more of pitch, resonance and amplitude and are altered, thereby providing tuning of the drum via manipulation of the one or more of the ITAs.

Accessories to improve the tonal qualities of a guitar or other stringed instruments include a bridge sound plate, a bridge support, a stress tube, and one or more bridge pin bolts. A bridge pin bolt may include a head, a shank, a thread, and a nut, the head of the bridge pin bolt having a void therethrough extending from a front of the head to a back of the head to receive a guitar string therethrough, the void extending upwardly from the front of the head to the back of the head. One or more of the accessories may be formed of brass or another material with good tonal properties. A sound plate may be adjustable or tunable. The accessories may be used independently, or may be used together as a system of accessories.
