Because of the importance of the major scale in modern music, the Lydian mode is often described as the scale that begins on the fourth scale degree of the major scale, or alternatively, as the major scale with the fourth scale degree raised half a step. This sequence of pitches roughly describes the scale underlying the fifth of the eight Gregorian (church) modes, known as Mode V or the authentic mode on F, theoretically using B♮ but in practice more commonly featuring B♭.[1] The use of the B♭ as opposed to B♮ would have made such piece in the modern-day F major scale.
Ancient Greek Lydian
The name Lydian refers to the ancient kingdom of Lydia in Anatolia. In Greek music theory, there was a Lydian scale or "octave species" extending from parhypate hypaton to trite diezeugmenon, equivalent in the diatonic genus to the modern Ionian mode (the major scale).[2]
In the chromatic and enharmonic genera, the Lydian scale was equivalent to C D♭ E F G♭ A B C, and C C E F F A B C, respectively,[3] where "" signifies raising the pitch by approximately a quarter tone.
Medieval Lydian mode
In the Middle Ages and Renaissance, this mode was described in two ways. The first way is the diatonic octave species from F up to F an octave above, divided at C to produce two segments:
The second is as a mode with a final on F and an ambitus extending to F an octave higher and in which the note C was regarded as having an important melodic function. Many theorists of the period observed that B♭ is used more typically than B♮ in compositions in Lydian mode.[1]
Modern Lydian mode
The Lydian scale can be described as a major scale with the fourth scale degree raised a semitone, making it an augmented fourth above the tonic; e.g., an F-major scale with a B♮ rather than B♭. That is, the Lydian mode has the following formula:
1, 2, 3, ♯4, 5, 6, 7, 8
This mode's augmented fourth and the Locrian mode's diminished fifth are the only modes to have a tritone above the tonic.
whole, whole, whole, half, whole, whole, half or (W-W-W-H-W-W-H)
Notable compositions in the Lydian mode
Classical (Ancient Greek)
The Paean and Prosodion to the God, familiarly known as the Second Delphic Hymn, composed in 128 BC by Athénaios Athenaíou is predominantly in the Lydian tonos, both diatonic and chromatic, with sections also in Hypolydian.[4]
A rare, extended use of the Lydian mode in the Classical repertoire is Simon Sechter's 1822 Messe in der lydischen Tonart (Mass in the Lydian Mode).[5] A more famous example from around the same time is the third movement of Ludwig van Beethoven's String Quartet No. 15 in A minor, Op. 132 (1825), titled by the composer "Heiliger Dankgesang eines Genesenen an die Gottheit, in der lydischen Tonart" ("Holy Song of Thanksgiving by a Convalescent to the Divinity, in the Lydian Mode").[6] The alternating passages in F use the Lydian scale with sharp fourth scale degree exclusively.
Charles-Valentin Alkan's Allegro barbaro (Étude Op. 35, No. 5, published in 1848) is written strictly in F Lydian, with no B♭'s present at all.[7]
Anton Bruckner employed the sharpened fourth of the Lydian scale in his motet Os justi (1879) more strictly than Renaissance composers ever did when writing in this mode.[8]
Gabriel Faure's song Lydia from "2 Melodies" Op 4 ?1872. This ode to Lydia - by Parnassian poet Leconte de Lisle - starts, appropriately, in the Lydian mode and, in F, has a raised 4th (B natural) in the first line of the melody.
Modern
In the 20th century, composers began once again to exploit modal scales with some frequency. George Enescu, for example, includes Lydian-mode passages in the second and third movements of his 1906 Decet for Winds, Op. 14.[9] An example from the middle of the century is the scherzo movement of Carlos Chávez's Symphony No. 3 (1951–54). The movement opens with a fugue subject, featuring extremely wide leaps, in C Lydian with following entries in F and G Lydian.[10]Alexei Stanchinsky wrote a Prelude in Lydian mode earlier in the 20th century.[11]
In practical terms it should be said that few rock songs that use modes such as the phrygian, Lydian, or locrian actually maintain a harmony rigorously fixed on them. What usually happens is that the scale is harmonized in [chords with perfect] fifths and the riffs are then played [over] those [chords].[13]

In music theory a diatonic scale is a heptatonic (seven-note) scale that includes five whole steps and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps. In other words, the half steps are maximally separated from each other.
In music theory, the term mode or modus is used in a number of distinct senses, depending on context.
The major scale is one of the most commonly used musical scales, especially in Western music. It is one of the diatonic scales. Like many musical scales, it is made up of seven notes: the eighth duplicates the first at double its frequency so that it is called a higher octave of the same note.
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 music theory, the tritone is defined as a musical interval spanning three adjacent whole tones. For instance, the interval from F up to the B above it is a tritone as it can be decomposed into the three adjacent whole tones F–G, G–A, and A–B.
An octatonic scale is any eight-note musical scale. However, the term most often refers to the ancohemitonic symmetric scale composed of alternating whole and half steps, as shown at right. In classical theory, this symmetrical scale is commonly called the octatonic scale, although there are a total of 43 enharmonically inequivalent, transpositionally inequivalent eight-note sets.
In music, modulation is the change from one tonality to another. This may or may not be accompanied by a change in key signature. Modulations articulate or create the structure or form of many pieces, as well as add interest. Treatment of a chord as the tonic for less than a phrase is considered tonicization.
Modulation is the essential part of the art. Without it there is little music, for a piece derives its true beauty not from the large number of fixed modes which it embraces but rather from the subtle fabric of its modulation.
A semitone, also called a minor second, 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. It is defined as the interval between two adjacent notes in a 12-tone scale, visually seen on a keyboard as the distance between two keys that are adjacent to each other. For example, C is adjacent to C♯; the interval between them is a semitone.
In music theory, an augmented sixth chord contains the interval of an augmented sixth, usually above its bass tone. This chord has its origins in the Renaissance, was further developed in the Baroque, and became a distinctive part of the musical style of the Classical and Romantic periods.
Chromaticism is a compositional technique interspersing the primary diatonic pitches and chords with other pitches of the chromatic scale. In simple terms, within each octave, diatonic music uses only seven different notes, rather than the twelve available on a standard piano keyboard. Music is chromatic when it uses more than just these seven notes.
Mixolydian mode may refer to one of three things: the name applied to one of the ancient Greek harmoniai or tonoi, based on a particular octave species or scale; one of the medieval church modes; or a modern musical mode or diatonic scale, related to the medieval mode.
The Aeolian mode is a musical mode or, in modern usage, a diatonic scale also called the natural minor scale. On the piano, using only the white keys, it is the scale that starts with A and continues to the next A only striking white keys. Its ascending interval form consists of a key note, whole step, half step, whole step, whole step, half step, whole step, whole step. That means that, in A aeolian, a scale would be played beginning in A, move up a whole step to B, move up a half step to C, then up a whole step to D, a whole step to E, a half step to F, a whole step to G, and a final whole step to a high A.
The Phrygian mode can refer to three different musical modes: the ancient Greek tonos or harmonia, sometimes called Phrygian, formed on a particular set of octave species or scales; the medieval Phrygian mode, and the modern conception of the Phrygian mode as a diatonic scale, based on the latter.
The Locrian mode is the seventh mode of the major scale. It is either a musical mode or simply a diatonic scale. On the piano, it is the scale that starts with B and only uses the white keys from there on up to the next higher B. Its ascending form consists of the key note, then: Half step, whole step, whole step, half step, whole step, whole step, whole step.
A heptatonic scale is a musical scale that has seven pitches, or tones, per octave. Examples include:
In music, polymodal chromaticism is the use of any and all musical modes sharing the same tonic simultaneously or in succession and thus creating a texture involving all twelve notes of the chromatic scale. Alternately it is the free alteration of the other notes in a mode once its tonic has been established.
In music, the major Locrian scale, also called the Locrian major scale, is the scale obtained by sharpening the second and third notes of the diatonic Locrian mode. With a tonic of C, it consists of the notes C D E F G♭ A♭ B♭. It can be described as a whole tone scale extending from G♭ to E, with F introduced within the diminished third interval from E to G♭. The scale therefore shares with the Locrian mode the property of having a diminished fifth above the tonic.
Diatonic and chromatic are terms in music theory that are used to characterize scales. The terms are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900.
The Lydian Chromatic Concept of Tonal Organization is a 1953 jazz music theory book written by George Russell. The book is the founding text of the Lydian Chromatic Concept (LCC), or Lydian Chromatic Theory (LCT). Russell's work postulates that all music is based on the tonal gravity of the Lydian mode.
A decatonic scale is a ten note musical scale. If the notes are ordered, a decatonic set has 3,628,800 permutations, however, in twelve tone equal temperament only six unordered ten note sets exist, 10-1—10-6:
