| == A-Team theory ==
| |
| Oneirotonic is often used as distorted diatonic. Because distorted diatonic modal harmony and functional harmony both benefit from a recognizable major third, the following theory essentially assumes an [[A-Team]] tuning, i.e. an oneirotonic tuning with generator between 5\13 and 7\18 (or possibly an approximation of such a tuning, such as a [[neji]]). The reader is encouraged to experiment and see what ideas work for other oneirotonic tunings.
| |
| === Ana modes ===
| |
| We call modes with a major mos5th ''ana modes'' (from Greek for 'up'), because the sharper 5th degree functions as a flattened melodic fifth when moving from the tonic up. The ana modes of the MOS are the 4 brightest modes, namely Dylathian, Illarnekian, Celephaïsian and Ultharian.
| |
|
| |
| The ana modes have squashed versions of the classical major and minor pentachords R-M2-M3-P4-P5 and R-M2-m3-P4-P5 and can be viewed as providing a distorted version of classical diatonic functional harmony. For example, in the Dylathian mode, the 4:5:9 triad on the sixth degree can sound like both "V" and "III of iv" depending on context.
| |
|
| |
| In pseudo-classical functional harmony, the 6th scale degree (either an augmented mossixth or a perfect mossixth) could be treated as mutable. The perfect mossixth would be used when invoking the diatonic V-to-I trope by modulating by a perfect mosfourth from the sixth degree "dominant". The augmented mossixth would be used when a major key needs to be used on the fourth degree "subdominant".

| |
| ==== Pentatonic subsets ====
| |
| The ''Oneiro Falling Suspended Pentatonic'', i.e. P1-M2-P4-M5-M7 (on J, J-K-M-N-P), is also an important subset in ana modes: it roughly implies the "least" tonality (In particular, it only implies ana-ness, not major or minor tonality), and it sounds floaty, and suspended, much like suspended and quartal chords do in diatonic contexts. The ''Oneiro Rising Suspended Pentatonic'' P1-M2-P4-P6-M7 (J-K-M-O-P) can be used for similar effect.
| |
|
| |
| Modes of the oneiro-pentatonic MOS:
| |
| # P1-M2-P4-M5-M7 Oneiro Falling Suspended Pentatonic
| |
| # P1-M2-P4-P6-M7 Oneiro Rising Suspended Pentatonic
| |
| # P1-m3-P4-P6-M7 Oneiro Symmetrical Pentatonic
| |
| # P1-m3-P4-P6-m8 Oneiro Expanding Quartal Pentatonic
| |
| # P1-m3-m5-P6-m8 Oneiro Diminished Pentatonic
| |
|
| |
| ==== Functional harmony ====
| |
| Oneiro has at least two different types of "V-to-I" resolution because of the two fifth sizes:
| |
| # One uses the sharp fifth as the "V" and uses a true major third. The sharp "V" voiceleads naturally to the flat fifth in the resolved falling tonic triad on the I: e.g. P6-M8-P2 > M5-P1-(M/m)3.
| |
| # One uses the flat fifth as the "V" and the chord on the "V" is a "false major triad" R-P4-P6 (root-falling 4th-rising 5th).
| |
|
| |
| Some suggested basic ana functional harmony progressions are listed below, outlined very roughly. Note that VI, VII and VIII are sharp 5th, 6th-like and 7th-like degrees respectively. A Roman numeral without maj or min means either major or minor. The "Natural" Roman numerals follow the Illarnekian mode.

| |
| ** I-IVmaj-II
| |
| ** I-VIImin-II
| |
| * Modulations by major mos3rd:
| |
| ** Modulate up major mos2nd twice
| |
| ** Imin-VImin-III (only in 13edo)
| |
| ** Imaj-&VImin-III (only in 13edo)
| |
| * Modulations by minor mos3rd:
| |
| ** I-VI-@III
| |
| ** I-IVmin-VImin-@VIIImaj-@III
| |
|
| |
| Another Western-classical-influenced approach to oneirotonic chord progressions is to let the harmony emerge from counterpoint.

| === Kata modes ===
| |
| We call modes with a minor mos5th ''kata modes'' (from Greek for 'down'). The kata modes of the MOS are the 4 darkest modes, namely Mnarian, Kadathian, Hlanithian and Sarnathian. In kata modes, the melodically squashed fifth from the tonic downwards is the flatter 5th degree. Kata modes could be used to distort diatonic tropes that start from the tonic and work downwards or work upwards towards the tonic from below it. For example:
| |
| * Mnarian (LSLSLLSL) and Kadathian (SLLSLLSL) are kata-Mixolydians
| |
| * Hlanithian (SLLSLSLL) is a kata-melodic major (the 4th degree sounds like a major third; it's actually a perfect mosfourth.)
| |
| * Sarnathian (SLSLLSLL) is a kata-melodic minor (When starting from the octave above, the 4th degree sounds like a minor third; it's actually a diminished mosfourth.)
| |
|
| |
| When used in an "ana" way, the kata modes are radically different in character than the ana modes. Particularly in 13edo and tunings close to it, the fifth and seventh scale degrees become the more concordant 11/8 and quasi-13/8 respectively, so they may sound more like stable scale functions. Hlanithian, in particular, may be like a more stable version of the Locrian mode in diatonic.

| |
| === Chords and extended harmony ===
| |
| Chords are given in oneirotonic MOS interval notation. For example, M5 means major mosfifth (squashed fifth).
| |
|
| |
| "Rising" means that a triad uses the perfect mos6th (major 5th); "falling" means that a triad uses a major mos5th (minor 5th)
