Protestant conversionary missionaries and colonialism

It appears that some recent work has found a health-giving relationship here:
For example, Mackenzie's campaign for Khama III was part of his 30-year effort to protect African land from white settlers. Mackenzie was not atypical. In China, missionaries worked to end the opium trade; in India, they fought to curtail abuses by landlords; in the West Indies and other colonies, they played key roles in building the abolition movement. Back home, their allies passed legislation that returned land to the native Xhosa people of South Africa and also protected tribes in New Zealand and Australia from being wiped out by settlers.
Given our tendency to think of nothing good when considering colonialism, this is a surprising result. Worth passing on I think.

Bill Morrow once quipped that the whole Old Testament is about governance - I think I agree with him - but what is healthy governance and how do we get there from here (where here is, even in our own world, a tendency towards self-preservation rather than governance).

Towards automating a draft of the music of the te'amim

Introduction to the concept, including the music for the section of Psalm 18 below, is here. The main problem is the association of note with syllable. [First test result is here]

'By the testimony of Mosheh Ben Asher himself, the Masoretes received the te’amim from the second-century BCE Elders of Bathyra'*. The Masoretes and the Elders of Bathyra were encoders and the code they have written is a linear largely unambiguous sequence of codes that requires only a small amount of look-ahead logic to convert into a musical score with libretto.

The base symbols are consonants, vowels, and hand-signals. Some of the 'consonants' behave differently from others, but only a few. Yod and vav are the trickiest and they come up in two different ways in the short example that follows. Some of the 'vowels' likewise have multiple functions, particularly the schwa, which may act like a vowel or silently close a syllable. The musical signs have two overall functions, establishing the 'current note', default is the tonic (for which we assume E), and ornamentation.

Here is the raw data. This is really quite useful. We will take it as read except that the meteg (aka silluq) is not a vowel but a note (the tonic).

So how does one derive an algorithm for conversion to music.  Read the Unicode in sequence from left to right, character by character,syllable by syllable.

Rules
  • A syllable always begins with a consonant.
  • A syllable always has one vowel.
  • A syllable ends when a consonant:schwa is found (closed syllable), or when a consonant:vowel is found that begins a new syllable.
  • There are exceptions - when a consonant masquerading as a vowel is found, it together with the vowel it accompanies acts as a vowel.
  • A schwa cannot close a syllable that only contains a schwa as its vowel.
  • Treat dashes (1470) as spaces.
Examples: The following is verse 20 of Psalm 18, Letteris edition
20 וַיּֽוֹצִ֘יאֵ֥נִי לַמֶּרְחָ֑ב
 יְ֝חַלְּצֵ֗נִי כִּ֘י חָ֥פֵֽץ בִּֽי
Right away we have an open syllable. We know this by looking ahead to the next syllable.
וַ is the first syllable followed by יּֽוֹ.  In the first syllable, the vav is acting as a consonant. In the second the vav is acting as a vowel. In the second syllable, the yod is a consonant. In the next syllable, צִ֘י the yod acts as a vowel. 
That first word has 5 syllables (and of course 5 vowels). The last two are אֵ֥ and נִי. The whole is pronounced va-yo-tsi-'ei-ni. Each obeys the rules. The one that looks like vowels only ('ei) begins with the alef, a glottal stop ('). That alef is the 'consonant'. Alef can also be effectively silent.

The music for this first word: va, is on the tonic. yo is on the tonic E (and marked by the silluq). tsi has an ornament of three notes relative to the tonic. 'ei has moved the current note to a F# (key signature is E minor). And ni stays on the F#.

Summary:
  • Verse = {words}, words delimited by space (regular or 1470) or dash (1475)
  • Word = {syllables}, syllables delimited by consonants and contain only one vowel
  • Consonant:schwa closes an open syllable if the vowel in the syllable is not a schwa
  • Consonant:vowel always opens a new syllable
  • Syllable has transcription (libretto / pronunciation) and notes
  • Notes may establish a new current note, or notes may be an ornament returning to the current note either on the current syllable or the next if it is on the current note.
The sequence of codes in decimal notation for the first word is (bold is music)
1493;1463; va
1497;1468;1469;1493;1465; yo
1510;1460;1432;1497; tsi
1488;1461;1445; 'ei
1504;1460;1497; ni
the remaining words of verse 20
1500;1463;1502;1468;1462;1512;1456;1495;1464;1425;1489; la-mer-xav (bet without dagesh is v)
note how the normal consonant with a schwa closes a syllable. The syllable xav is on the subdominant (atnah), a resting point in most verses.
1497;1456;1437;1495;1463;1500;1468;1456;1510;1461;1431;1504;1460;1497; ye-xal-tsei-ni
1499;1468;1460;1432;1497; ki
1495;1464;1445;1508;1461;1469;1509; xa-phets
1489;1468;1460;1469;1497;1475; bi (bet with dagesh and silluq)
and here is the music with English libretto. Even in a close translation, the Hebrew and English will not correspond. A draft will be in Hebrew with one note per syllable except for ornaments which are melismatic. Likely in this case the English underlay moves back to the tonic too soon. The tonic should be on the 'me' and not on the delighted.
The remainder of Psalm 18:21-25 is below, work in process data for the analysis of syllables and notes using Unicode to create an algorithm to output Music XML. Dashes show the syllables in the number sequences. Red 1456 is the schwa that closes a syllable - ask why. No example here of final guttural for reversal of noun for transcription.
Note: for transliteration, this site may be useful - has open-source code. No music of course.

Recall - codes from 1488 to 1506 are consonants (except yod and vav, alef and heh where noted)
codes from 1456 to 1468 are vowels - transcription is not yet smart - could use phonetic standards.
codes from 1420 to 1453 are musical notes - ornaments and fundamentals are noted here.
