============================================================================= = Scales and Modes in Scottish Traditional Music = = Jack Campin = ============================================================================= Tetrachords and Pentachords =========================== For music theorists back as far as the ancient Greeks and as recently as present-day ethnomusicologists, it has often been useful to think of modes as constructed from smaller pieces; two chunks each spanning a fourth or a fifth. This reduces the number of modes you need to think about, since the pieces can be put together in different orders. Curt Sachs, in his book "The Rise of Music in the Ancient World", theorizes that melodies gradually expanded in range from the earliest times, starting with tunes using very few notes, called "oligotonic" by some theorists. These are found in music from many parts of the world. In Maori music they seem to have arisen independently. Unlike anywhere else in the world, pre-European New Zealand had an ecosystem dominated by birds, where birdsong was never silent anywhere and filled the forests with a volume of sound no human instrument could outplay. Maori music adapted to it by creating melodies that stayed within the narrow range used by birds, with the expressive interest created by delicate microtonal inflections and variations of ornamentation. All human music was effectively a concerto with a bird orchestra. But the music of peoples related to the Maori, in Polynesia and south-east Asia, uses wider range; the oligotonic idiom isn't necessarily a mark of the ancient and primitive, and for the Maori it can only be a thousand years old, younger than some notated Western chant. At some point in the history of many Asian and European musics there was a divergence in oligotonic music into two "oligo-modes" (this is not standard terminology). One type of narrow-range melody spans a fourth, with the tonal centre at the top (so a melody may fall at the start after the tonal centre has been established, and will rise at the end to meet it), and the other spans a fifth, with the tonal centre at the bottom (so that a melody tends to rise at the start and fall at its close). Within these spans, a variety of inner notes were added. There were other possibilities. Chants used for the Hindu Sama Veda seem to be a relic of a fourth-span melody type from ancient times: its melodies usually descend from the fourth, and may have tightly clumped microtonal intervals at the bottom of the range. It may derive from a period when only the extreme pitches of a tune were consistent, and those within the tetrachord could be varied at will. The ancient Greek ENHARMONIC and INTENSE CHROMATIC tetrachords were similar to those of the Sama Veda, but the Greeks didn't write down any melodic examples of them or pass any on in tradition. At some later stage tetrachords and pentachords were combined into scales of a full octave, in one of two ways. Putting the pentachord at the bottom and the tetrachord at the top gave an authentic mode (with the tonal centre at both ends) and the opposite procedure (historically older) gave a plagal mode. Sometimes other things could happen. The SABA tetrachord of Middle Eastern music was (and still is) usually extended upwards to a scale with no pure octave - the 8th step of the scale is about a semitone flat. This construction was done in hardware in some kinds of ancient music - double flutes or shawms had a tetrachord in one hand and a pentachord on the other, and you could create composite modes by choosing two appropriate instruments. (The fingering was like a Highland pipe: at any moment, one or other hand was always fully closed, and since the overall length of both pipes was the same, each pipe acted as a drone for the other). In Greece the double shawm (aulos) was frequently depicted in art; it survives as the triple pipe of Sardinia, the launeddas (it has a third pipe, a lower drone without fingerholes). An instrument like the launeddas is depicted on a Pictish stone, so the idea may have been used in Scotland before either the Gaels or the Saxons got here, though there isn't much trace of it now. This list of tetrachords and pentachords is set up for constructing modes with tonal centre A, using Sachs's approach. So the tetrachords have A at the top and the pentachords have A at the bottom. The names correspond to the heptatonic modes you can make from them - in Scottish music the lydian and phrygian pentachords only match with one possible tetrachord, whereas the other pentachords and all three tetrachords have two possible partners. It's like an addition table: TTS TST STT TTTS lyd - - TTST maj mix - TSTT - dor min STTT - - phr X:0 T:The Lydian/Major Tetrachord, TTS M:6/4 L:1/4 K:A "_do"E2 "_re"F "_mi"G "_fa"A2 |\ "_fa"A2 "_mi"G "_re"F "_do"E2|] X:0 T:The Mixolydian/Dorian Tetrachord, TST M:6/4 L:1/4 K:ADor "_re"E2 "_mi"F "_fa"G "_so"A2 |\ "_so"A2 "_fa"G "_mi"F "_re"E2|] X:0 T:The Minor/Phrygian Tetrachord, STT M:6/4 L:1/4 K:AMin "_mi"E2 "_fa"F "_so"G "_la"A2 |\ "_la"A2 "_so"G "_fa"F "_mi"E2|] X:0 T:The Lydian Pentachord, TTTS M:7/4 L:1/4 K:ALyd "_fa"A2 "_so"B "_la"c "_ti"d "_do"e2 |\ "_do"e2 "_ti"d "_la"c "_so"B "_fa"A2|] X:0 T:The Major/Mixolydian Pentachord, TTST M:7/4 L:1/4 K:A "_do"A2 "_re"B "_mi"c "_fa"d "_so"e2 |\ "_so"e2 "_fa"d "_mi"c "_re"B "_do"A2|] X:0 T:The Dorian/Minor Pentachord, TSTT M:7/4 L:1/4 K:AMin "_re"A2 "_mi"B "_fa"c "_so"d "_la"e2 |\ "_la"e2 "_so"d "_fa"c "_mi"B "_re"A2|] X:0 T:The Phrygian Pentachord, STTT M:7/4 L:1/4 K:APhr "_mi"A2 "_fa"B "_so"c "_la"d "_ti"e2 |\ "_ti"e2 "_la"d "_so"c "_fa"B "_mi"A2|] These can be gapped in the same way as modes spanning a full octave. Narrow range is typical of children's songs all over the world, so it makes sense to look for tetrachordal or pentachordal structures in Scottish children's songs too. This song from 1950s Edinburgh is TTS-tetrachordal with an added (unimportant) note above the tonal centre: X:0 T:One Two Three A-Leerie G:children's game song B:James Ritchie: The Golden City M:C| L:1/8 Q:1/2=84 K:C G2G2 GccB|A2A2 AddB | G2G2 GccB|AdAB c2c2|] while this one is gapped pentachordal, TTm: X:0 T:How Many Miles to Babylon?

This pentachordal tune is a klezmer dance from southern Ukraine. It uses a TTST pentachord most of the time with a break in the TSTT pentachord. Very few klezmer tunes are modally like this and its origins are unknown.

Some old Scottish tunes, like "Killiecrankie", have a similar form. In the first half of this tune there is a melodic core that stays within the lower tetrachord, with the upper tetrachord used in a more stereotyped way, as a descending scale, only after the basic idea of the tune is established. Some of the higher notes sound as if they've been jumped up an octave as a trick dramatic effect, which stuck as part of the tune.

Song tunes don't often do that strictly: an instrument with wider range than the voice is more effective at drastic changes of register. But there are many songs where for a few bars at a time, only a few exceptional notes fall outside the tetrachord. This song (mixolydian/dorian hexatonic, also used as an instrumental strathspey, as a reel, and in Ireland as a polka) has fairly sharp separation of pitch ranges except for the closing bar: X:0 T:The Haughs of Cromdale S:Hamish Henderson's singing, via "101 Scottish Songs" M:4/4 L:1/8 Q:1/4=100 K:CDor B/A/|GC D>F G>F D>F |GC DC C(D/F/) G>F DF |GF BD C2 C3/|| d/|Cc c(B/A/) BB c(B/A/)|B>c BG F(G/A/) B>F | Gc c(B/A/) Bd c(B/A/)|GF BD C2 C |] With song tunes, one frequent pattern is a four-line one, AABA, where the A lines have similar contours in a low tetrachord and the B one is in a higher range. This (lydian/major/mixolydian pentatonic) tune uses the same structure, though the subranges are hexachords: X:0 T:Farewell to Tarwathie M:C L:1/4 Q:1/4=120 K:G G |B G G|E D D|E G A |B2 G/G/|B G G|EA|B>B D>D G>B B>B|A>G G>G G3 B |c>d e>d dB|d>B Ad e>d d2 B>c|d>B A>G A2 G>A|B>B D>D G/A/B B>B|A>G G>G G2|] This English song uses a less symmetrical pitch arrangement - a lower seventh and an upper tetrachord - but the same ABBA structure. (It's effectively pentatonic: the fourth and seventh only occur as "pien" passing notes).

The result is an oddly indefinite ending in each part, with the last note producing a dominant-like unresolved effect in both, as if the first part was centred on G and the second part on F. If you were adding a chordal accompaniment, it might be an idea to put the final D minor chord in each part into some sort of inversion, to de-emphasize D as a tonal centre and preserve the calculated ambiguities of the tune.

Typically one tetrachord of the mode will change at a time, and the tune will stay within the new tetrachord for long enough for the listener to register the change before it expands in range again. This resembles the way Scottish music tends to shift mode in small steps, though there's no historical connection and the effect can be very different. ============================================================================= == (c) Jack Campin http://www.campin.me.uk/ June 2016 == == 11 Third Street, Newtongrange, Midlothian EH22 4PU, Scotland == == == == these pages: http://tinyurl.com/scottishmodes == =============================================================================
