Coda Coda (Italian for "tail", plural code) is a term used in music in a number of different senses, primarily to designate a passage that brings a piece (or a movement) to an end. Technically, it is an expanded cadence. It may be as simple as a few measures, or as complex as an entire section.

D. S. In music notation, Dal segno (Italian pronunciation: [dal ˈseɲɲo], English: /ˌdæl ˈseɪnjoʊ/ or /ˈsɛɡnoʊ/) (often abbreviated D.S.) is used as a navigation marker. From Italian for "from the sign," D.S. appears in sheet music and instructs a musician to repeat a passage starting from the sign shown at right, sometimes called the "segno" in English
Diatonic Passing Tone (dpt)

Expansion Substitution
The use of a different chord in addition to the original chord.
Equal Temperament
An equal temperament is a musical temperament, or a system of tuning, in which every pair of adjacent notes has an identical frequency ratio. As pitch is perceived roughly as the logarithm of frequency, this means that the perceived "distance" from every note to its nearest neighbor is the same for every note in the system.

Leading Tone
The seventh note of a scale or the chord built on that note.
Leap Recovery
A melodic device which suggests that a melody reverses its direction after a leap.
A melodic device in which the distance between two consecutive notes is 2 and 1/2 steps or more. Usually followed by a Leap Recovery
In musical notation the Italian word legato (literally meaning "tied together") indicates that musical notes are played or sung smoothly and connected. That is, in transitioning from note to note, there should be no intervening silence. Legato technique is required for slurred performance, but unlike slurring (as that term is interpreted for some instruments), legato does not forbid re articulation. In standard notation legato is indicated either with the word legato itself, or by a slur (a curved line) under the notes that are to be joined in one legato group. Legato, like staccato, is a kind of articulation. There is an intermediate articulation called either mezzo staccato or non-legato.
Locrian scale

The third note of a scale or the chord built on that note.
Melodic Contour
A graphic representation of a melody created by connecting the successive notes of a melody with a line.
Melodic Minor Scale
The melodic minor scale is the same as the natural minor with the exception that the sixth and seventh tones are raised by a semitone (half step) when the scale is ascending. While some composers, notably Mozart, have used this interval to advantage in melodic composition, other composers, having felt it to be an awkward leap, particularly in vocal music, considered a whole step between these two scale degrees more conducive to smooth melody writing, so either the sixth scale degree was raised or the seventh flattened.
Minor 6 (m6)
A 4 part chord consisting of 1 b3 5 6.
Minor 7 (m7)
A 4 part chord consisting of 1 b3 5 b7.
Minor Chord
A triad consisting of 1 b3 5.
Minor Large 7 (mL&)
A 4 part chord consisting of 1 b3 5 7.

Power 5
A chord consisting of only roots and perfect fifths. Technically not a chord by the standard chord definition.
All related activities of coordinating the process of recording music, video or putting on a concert or show.
Picardy Third
A Picardy third (also known as Tierce de Picardie) is a harmonic device. It refers to the use of a major chord of the tonic at the end of a musical section which is either modal or in a minor key. Basically the expected minor resolution is major instead.


Needed an entry for Q - so went with the British term for a quarter note.

An eighth note (American) or a quaver (British) is a musical note played for half the value of a quarter note (crotchet) and twice that of the sixteenth note (semiquaver), which amounts to one quarter the duration of a half note (minim), one eighth the duration of whole note (semibreve), one sixteenth the duration of a double whole note (breve), and one thirty-second the duration of a longa, hence the name.


The high and low note of a piece of music. The high and low notes of a melody or a melodic phrase.
Reentrant tuning
A reentrant tuning is a tuning of a stringed instrument where the strings (or more properly the courses on coursed instruments) are not ordered from the lowest pitch to the highest pitch (or vice versa). A break in an otherwise ascending (or descending) order of string pitches is known as a reentry. Most common reentrant tunings have only one reentry; In the case of the soprano ukulele, for example, the reentry is between the third and fourth strings, while in the case of the Venezuelan cuatro it is between the first and second strings.
A musical effect created by retaining the original melody while rewriting the original chord progression.
Relative Minor
The minor key, chord or scale based on the sixth degree of any major scale.
The reuse of an identical melody, phrase, chord progression or rhythm.
Replacement Substitution
The use of a different chord instead of the original chord.


As a sequence of musical notes in ascending and descending order. Most commonly, the notes of a scale will belong to a single key, used to conveniently represent part or all of a musical work including melody and/or harmony.
Second Ending transitional part of a song that typically connects the second theme to the first Theme.
A semitone, also called a half step or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. Think Jaws, Twilight Zone or any secret agent inspired theme.
A melodic device that uses parallel melodies starting on consecutive scale degrees.
Seventh (7)
A chord designation for a 4 part chord consisting of 1 3 5 b7.
Sixth (6)
A chord designation for a 4 part chord consisting of 1 3 5 6.
A system of melodic organization that uses syllables (DO RE MI FA SOL LA TI DO) to designate pitches. Two common systems are Moveable-DO Solfege and Fixed-DO Solfege.
A single melody on a chord progression with lyrics, if vocal.
The basic product of the music industry. A song consists of four elements: 1) title 2) melody 3) chords 4) lyrics (if vocal).
Staccato (Italian for detached) is a form of musical articulation. In modern notation it signifies a note of shortened duration, separated from the note that may follow by silence.
Stress Tone
A series of techniques used to bring attention to a specific. Stress can be applied to a note in the following ways: begin on it, end on it, sustain it, accent it, overplay it, place it on a down beat, embellish it.
The fourth note of a scale or the chord built on that note.
The sixth note of a scale or the chord built on that note.
The second note of a scale or the chord built on that note.
To let a note ring out.
Balance in music.


Tension is created melodically, harmonically or rhythmically. Each element seeks a resting point. That resting point is the resolution.
Tertiary Form
A song writing form using three themes.
Traditionally, a tetrachord (Greek: τετράχορδo) is a series of three smaller intervals filling in the interval of a perfect fourth, a 4:3 frequency proportion. In modern usage a tetrachord is any four-note segment of a scale or tone row. ( more info on Wikipedia )
Tonic Minor
The minor key, chord or scale based on the root of any major scale.
A triad, 'tri' meaning three, is a three note chord. In music, a triad is traditionally a set of three notes that can be stacked in thirds.

When stacked in thirds, the triad's members, from lowest pitched tone to highest, are called: the root, the third – its interval above the root being a minor third (three semitones) or a major third (four semitones) and the fifth – its interval above the third being a minor third or a major third, hence its interval above the root being a diminished fifth (six semitones), perfect fifth (seven semitones), or augmented fifth (eight semitones).


A harmonic principle using a temporary implied key change with an eventual return the the original key. The unresolved progression uses active chords only.


The strongest resolving progression in western, tonic-dominant music.


Whole Tone
A major second. This is a musical interval spanning two semitones, and encompassing two adjacent staff positions. For example, the interval from C to D is a major second or whole tone apart, as the note D lies two semitones above C, and the two notes are notated on adjacent staff positions.
Whole Tone Scale
A symmetrical scale with each interval a major second apart. There are only two whole tone scales. The scale step pattern is 1, 1, 1, 1, 1, 1


Jsut like Q I didn't have an entry for X - So I went with Xylophone - a musical instrument in the percussion family that consists of wooden bars struck by mallets.
