An improved tuning method for fixed interval musical instruments is provided. This Precise Temperament tuning method provide mathematically consistent intervals between notes to prevent dissonance within chords while retaining the esthetics of pure tones associated with Western music.

An automatic performance device executing a process includes: determining stochastically one of a plurality of timing patterns indicating a sound production timing of a musical instrument sound, and determining a musical instrument tone designation table associated with the determined timing pattern from a plurality of musical instrument tone designation tables.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

An electronic device modifies a first media content item by superimposing a first set of data over a first accented musical event. The first accented musical event has a first audio profile. The first set of data has a second audio profile configured to be masked by the first audio profile during playback of the first media content item. The electronic device transmits, to a second electronic device, the modified first media content item.
