In music theory, a tetrachord is a series of four notes separated by three intervals. In traditional music theory, a tetrachord always spanned the interval of a perfect fourth, a 4:3 frequency proportion —but in modern use it means any four-note segment of a scale or tone row, not necessarily related to a particular tuning system.
The Turkish makam is a system of melody types used in Turkish classical music and Turkish folk music. It provides a complex set of rules for composing and performance. Each makam specifies a unique intervalic structure and melodic development (seyir). Whether a fixed composition or a spontaneous composition, all attempt to follow the melody type. The rhythmic counterpart of makam in Turkish music is usul.

The Hypolydian mode, literally meaning "below Lydian", is the common name for the sixth of the eight church modes of medieval music theory. The name is taken from Ptolemy of Alexandria's term for one of his seven tonoi, or transposition keys. This mode is the plagal counterpart of the authentic fifth mode.
The Hypodorian mode, a musical term literally meaning 'below Dorian', derives its name from a tonos or octave species of ancient Greece which, in its diatonic genus, is built from a tetrachord consisting of a semitone followed by two whole tones. The rising scale for the octave is a single tone followed by two conjoint tetrachords of this type. This is roughly the same as playing all the white notes of a piano from A to A: A | B C D E | (E) F G A. Although this scale in medieval theory was employed in Dorian and Hypodorian, from the mid-sixteenth century and in modern music theory they came to be known as the Aeolian and Hypoaeolian modes.
Echos is the name in Byzantine music theory for a mode within the eight-mode system (oktoechos), each of them ruling several melody types, and it is used in the melodic and rhythmic composition of Byzantine chant, differentiated according to the chant genre and according to the performance style. It is akin to a Western medieval tonus, an Andalusian tab', an Arab naġam, or a Persian parde.
In traditional Arabic music theory, a jins is a set of three, four, or five stepwise pitches used to build an Arabic maqam, or melodic mode. They correspond to the English terms trichord, tetrachord, and pentachord. A maqam is made up of two or more ajnas.
In music, the dominant is the fifth scale degree of the diatonic scale. It is called the dominant because it is second in importance to the first scale degree, the tonic. In the movable do solfège system, the dominant note is sung as "So(l)".
In music, the Ukrainian Dorian scale is a modified minor scale with raised 4th and 6th, and lowered 7th degrees, often with a variable 4th degree. It has traditionally been common in the music of Eastern Europe, Southeast Europe, and the Mediterranean including Jewish, Greek, Ukrainian, and Romanian music. Because of its widespread use, this scale has been known by a variety of names including Altered Dorian, Hutsul mode and Mi Shebeirach. It is also closely related to the Nikriz pentachord found in Turkish or Arabic maqam systems.
Oktōēchos is the name of the eight mode system used for the composition of religious chant in Byzantine, Syriac, Armenian, Georgian, Latin and Slavic churches since the Middle Ages. In a modified form the octoechos is still regarded as the foundation of the tradition of monodic Orthodox chant today.
The tone clock, and its related compositional theory tone-clock theory, is a post-tonal music composition technique, developed by composers Peter Schat and Jenny McLeod. Music written using tone-clock theory features a high economy of musical intervals within a generally chromatic musical language. This is because tone-clock theory encourages the composer to generate all their harmonic and melodic material from a limited number of intervallic configurations. Tone-clock theory is also concerned with the way that the three-note pitch-class sets can be shown to underlie larger sets, and considers these triads as a fundamental unit in the harmonic world of any piece. Because there are twelve possible triadic prime forms, Schat called them the "hours", and imagined them arrayed in a clock face, with the smallest hour in the one o'clock position, and the largest hour in the 12 o'clock position. A notable feature of tone-clock theory is tone-clock steering: transposing or inverting hours so that each note of the chromatic aggregate is generated once and once only.
Saba is a kind of musical scale used in both Arabic music and Turkish classical music. This article covers both the Arabic jins and maqam called "Saba" as well as the similar Turkish makam of the same name.
The Rast pitch class set is a set of scales that are named after the Rast makam. For Rast, there is the Rast tetrachord and Rast pentachord.
In Turkish classical music, the Nikriz pitch class set is a set of scales that are named after the Nikriz makam. For Nikriz, there is only the pentachord, as the 4th is raised. The Nikriz pentachord is the same as putting the 53-TET equivalent of a whole step in the beginning of the Hicaz tetrachord.
Geçki is the usage of a different makam during the performance of another makam, which may or may not lead to a modulation. It is a form of modal interchange, used specifically within Turkish makam music.
In Turkish classical music, the Buselik pitch class set is a set of scales that are named after the Buselik makam. For Buselik, there is the Buselik tetrachord and the Buselik pentachord.
In Turkish classical music, the Uşşak pitch class set is a set of scales that are named after the Uşşak or Hüseynî makams. For Uşşak, there is the Uşşak tetrachord and the Hüseynî pentachord. While in Arabic maqam music, maqam Bayati is taken as a basic tetrachord, in Turkish makam music, Uşşak is taken as a basic tetrachord instead.
In Turkish classical music, the Çârgâh pitch class set is a set of scales that are named after the Çârgâh makam. For Çârgâh, there is the Çârgâh tetrachord and the Çârgâh pentachord.
In Turkish classical music, the Kürdî pitch class set is a set of scales that are named after the Kürdî makam. For Kürdî, there is the Kürdî tetrachord and the Kürdî pentachord.
