Musical note in the context of "Electronic musical instrument"

A music box (American English) or musical box (British English) is an automatic musical instrument in a box that produces musical notes by using a set of pins placed on a revolving cylinder or disc to pluck the tuned teeth (or lamellae) of a steel comb. The popular device best known today as a "music box" developed from musical snuff boxes of the 18th century and were originally called carillons à musique (French for "chimes of music"). Some of the more complex boxes also contain a tiny drum and/or bells in addition to the metal comb.

The incipit (/ˈɪnsɪpɪt/ IN-sip-it) of a text is the first few words of the text, employed as an identifying label. In a musical composition, an incipit is an initial sequence of notes, having the same purpose. The word incipit comes from Latin and means "it begins". Its counterpart taken from the ending of the text is the explicit (Latin: explicitum est, lit. 'it has been unfolded'). The unfolding refers to a papyrus scroll. The end is also referred to as desinit, 'it is finished'.

Before the development of titles, texts were often referred to by their incipits, as with for example Agnus Dei. During the medieval period in Europe, incipits were often written in a different script or colour from the rest of the work of which they were a part, and "incipit pages" might be heavily decorated with illumination. Though the word incipit is Latin, the practice of the incipit predates classical antiquity by several millennia and can be found in various parts of the world. Although not always called by the name of incipit today, the practice of referring to texts by their initial words remains commonplace.

In music, a counter-melody (often countermelody) is a sequence of notes, perceived as a melody, written to be played simultaneously with a more prominent lead melody. In other words, it is a secondary melody played in counterpoint with the primary melody. A counter-melody performs a subordinate role, and it is typically heard in a texture consisting of a melody plus accompaniment.

In marches, the counter-melody is often given to the trombones or horns. American composer David Wallis Reeves is credited with this innovation in 1876.

In music, timbre (/ˈtæmbər, ˈtɪm-, ˈtæ̃-/), also known as tone color or tone quality (from psychoacoustics), is the perceived sound of a musical note, sound or tone. Timbre distinguishes sounds according to their source, such as choir voices and musical instruments. It also enables listeners to distinguish instruments in the same category (e.g., an oboe and a clarinet, both woodwinds).

In simple terms, timbre is what makes a particular musical instrument or human voice have a different sound from another, even when they play or sing the same note. For instance, it is the difference in sound between a guitar and a piano playing the same note at the same volume. Both instruments can sound equally tuned in relation to each other as they play the same note, and while playing at the same amplitude level each instrument will still sound distinctive with its own unique tone color. Musicians distinguish instruments based on their varied timbres, even instruments playing notes at the same pitch and volume.

In Western music theory, a chord is a group of notes played together for their harmonic consonance or dissonance. The most basic type of chord is a triad, so called because it consists of three distinct notes: the root note along with intervals of a third and a fifth above the root note. Chords with more than three notes include added tone chords, extended chords and tone clusters, which are used in contemporary classical music, jazz, and other genres.

Chords are the building blocks of harmony and form the harmonic foundation of a piece of music. They provide the harmonic support and coloration that accompany melodies and contribute to the overall sound and mood of a musical composition. The factors, or component notes, of a chord are often sounded simultaneously but can instead be sounded consecutively, as in an arpeggio.

In music theory, counterpoint is the relationship of two or more simultaneous musical lines (also called voices) that are harmonically dependent on each other, yet independent in rhythm and melodic contour. The term originates from the Latin punctus contra punctum meaning "point against point", i.e. "note against note".

John Rahn describes counterpoint as follows:

In musical notation, a beam is a horizontal or diagonal line used to connect multiple consecutive notes (and occasionally rests) to indicate rhythmic grouping. Only eighth notes (quavers) or shorter can be beamed. The number of beams is equal to the number of flags that would be present on an unbeamed note. Beaming refers to the conventions and use of beams. A primary beam connects a note group unbroken, while a secondary beam is interrupted or partially broken.

Traditionally in Western music, a musical tone is a steady periodic sound. A musical tone is characterized by its duration, pitch, intensity (or loudness), and timbre (or quality). The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation.

A simple tone, or pure tone, has a sinusoidal waveform. A complex tone is a combination of two or more pure tones that have a periodic pattern of repetition, unless specified otherwise.

In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord.

In Western music, intervals are most commonly differencing between notes of a diatonic scale. Intervals between successive notes of a scale are also known as scale steps. The smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones. They can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, between enharmonically equivalent notes such as C♯ and D♭. Intervals can be arbitrarily small, and even imperceptible to the human ear.

In music, a step, or conjunct motion, is the difference in pitch between two consecutive notes of a musical scale. In other words, it is the interval between two consecutive scale degrees. Any larger interval is called a skip (also called a leap), or disjunct motion.

In the diatonic scale, a step is either a minor second (sometimes also called half step) or a major second (sometimes also called whole step), with all intervals of a minor third or larger being skips. For example, C to D (major second) is a step, whereas C to E (major third) is a skip.
