What are church modes in music?
Church modes are scalar arrangements of whole and half tones that Medieval theorists derived most likely from early Christian vocal convention. The Western church integrated the tetrachordal principle into the doctrine of ascending church modes, based on the constituent pitches of the tetrachord d–e–f–g, which furnishes the first step, or finalis, for each of the four modal pairs, authentic and plagal.
Gregorian chants are based on eight different modes, often called church modes. Seven were given names identical to those used in the musical theory of ancient Greece: Dorian, Hypodorian, Phrygian, Hypophrygian, Lydian, Hypolydian, and Mixolydian, while the eighth mode, Hypomixolydian, was adapted from the Greek. Each mode comprises a diatonic scale with the compass of one octave and are classified by their finalis, the usual final note of a melody in that mode.

Where and when were church modes first used?
Church modes, scalar arrangements of whole and half tones, were derived by medieval theorists, likely from early Christian vocal convention.
The Eastern church was influenced by ancient Hebrew modal music, with basic chant formulas codified in the 8th century into a system known as oktōēchos, suggested by St. John of Damascus. The Western church retained Greek musical concepts, integrating the tetrachordal principle into ascending church modes. Originally, church modes were known by their respective numbers. The application, or rather misapplication, of the Greek names dates from a 9th-century treatise attributed to the monk Hucbald.

How many church modes are there, and what are their names?
Medieval theorists defined eight church modes that consist of scalar arrangements of whole and half tones. The Western church integrated the concept of tetrachords into a doctrine of ascending church modes. Each mode has a finalis and a recitation tone, or tenor.
The mature modal system is represented as follows:
* Dorian: D-e-f-g-a-b-c-d
* Hypodorian: A-b-c-d-e-f-g-a
* Phrygian: E-f-g-a-b-c-d-e
* Hypophrygian: B-c-d-e-f-g-a-b
* Lydian: F-g-a-b-c-d-e-f
* Hypolydian: C-d-e-f-g-a-b-c
* Mixolydian: G-a-b-c-d-e-f-g
* Hypomixolydian: D-e-f-g-a-b-c-dIn 1547, Henricus Glareanus expanded the system to include twelve modes in Dodecachordon, including the Aeolian and Ionian modes.

How do church modes differ from the major and minor scales we use today?
Church modes differ from major and minor scales through their unique arrangements of whole and half steps, which gives each mode a distinct melodic character. Unlike major and minor scales that have a defined tonal center and harmonic function, church modes, also known as Gregorian chants, emphasize melody rather than harmony.
Each church mode is characterized by its finalis (the main note of the mode) and a recitation tone (tenor or confinalis). The modes are defined by their intervallic structure relative to the finalis, creating different patterns of whole and half steps. In contrast, major and minor scales have specific, consistent patterns of whole and half steps that define their sound and harmonic behavior.

How did composers use church modes in early music?
In early music, composers used church modes primarily for melodic rather than harmonic purposes, maintaining their purity even beyond the era of monophonic chant. During the Renaissance, composers preserved the integrity of traditional modality in polyphony by using musica falsa and musica ficta to add accidentals that would circumvent the modal image offered by the musical text.
The strict consistency of church modes weakened with the use of tones not originally included in the basic scale pattern. This occurred because medieval musicians sought to avoid the tritone F–B, which was considered undesirable. The substitution of B♭ for B♮ changed the character of a mode.

Why did the use of church modes decline, and what replaced them in Western music?
The use of church modes declined due to the weakening of their strict consistency through the introduction of accidentals, like B♭, to avoid undesirable intervals. This alteration paved the way for the emergence of major and minor modes.
As polyphonic music grew in complexity, the distinction between authentic and plagal modes became less relevant, reducing the number of modes to six. Eventually, the dual major-minor system, known as tonality, replaced the old ecclesiastical modes, dominating 18th- and 19th-century harmony. Some 20th-century works and folk songs revived the patterns of the old church modes.

church mode, in music, any one of eight scalar arrangements of whole and half tones, derived by medieval theorists, most likely from early Christian vocal convention.
The Eastern church was doubtless influenced by ancient Hebrew modal music. Its basic chant formulas were codified as early as the 8th century into a system known as oktōēchos, first suggested by St. John of Damascus (d. 749), according to the Byzantine treatise Hagiopolites (“From the Holy City”). The Byzantine arrangement of four authentic and four plagal ēchoi was probably inspired by an even earlier Syrian oktōēchos; whether the latter was, as some assert, a direct outgrowth of the ancient Greek modes remains uncertain, although the concept of mode itself had certainly been handed down from antiquity.
The Western church, too, retained certain Greek musical concepts for its own purposes. Unable to make use of the ancient octave species with its descending tetrachords, that church nevertheless integrated the tetrachordal principle into the doctrine of ascending church modes, based on the constituent pitches of the tetrachord d–e–f–g, which furnishes the first step, or finalis, for each of the four modal pairs, authentic and plagal. Whereas authentic modes begin and end with the finalis, their plagal partners range from the fourth below to the fifth above the finalis. Each mode, however, is characterized not only by its finalis but also by a unique recitation tone, tenor or confinalis—the upper fifth for authentic modes and the third for plagal (except where other considerations, such as the avoidance of intonation problems, prevail). Originally, the church modes were known by their respective numbers. The application, or rather misapplication, of the Greek names dates from a 9th-century treatise attributed to the monk Hucbald.

Schematically, the mature modal system may be represented as follows (with the finals underlined and the confinals or tenors in lowercase letters):
Though responsive primarily to melodic rather than harmonic needs, modality, for reasons of an essentially philosophical nature (modality purity), retained its hold upon composers well beyond the era of monophonic chant proper. By the same token, Renaissance polyphony turned to various subterfuges in order to preserve the integrity of traditional modality, while acknowledging the harmonically generated mandate to provide for the necessary leading tones (cadential halftone steps). Musica falsa and musica ficta were contrived as means of circumventing the modal image offered by the musical text through the addition of accidentals, according to certain generally accepted rules. In the later 16th century the Swiss humanist Henricus Glareanus, yielding to the musical realities of his day, proposed two new pairs of modes, Aeolian (corresponding to natural minor) and Ionian (identical with the major scale), for a total of 12 modes (hence the title of his book, Dodecachordon).
After more than two centuries of primarily didactic significance, modality attracted renewed attention in the late 19th and early 20th centuries, not only because it served the purposes of composers of neo-medieval or neo-Renaissance persuasion but also because it allowed purely melodic forces to reassert themselves at a time when functional harmony in the West appeared to have reached its zenith and when, moreover, previously unexploited folk traditions had begun to influence academic music. Precisely because, unlike the diatonic major and minor scales, the church modes are fundamentally impervious to the dictates of Western harmony, they continue to be useful referents in the analysis of any number of folk music strains, including that of the Anglo-American ballad.
