jan Akersimun: Well, actually, I meant to pair up the 16 possible syllables of Silbo Gomera (4 vowels and 4 consonants) arbitrarily with the 15 catch-all syllables from (this first scheme of mine is not just a shorthand but a kind of compression technique, akin to the letter codes jan ante worked on) but spelling out the words works too. I hadn't thought of that. :O If we use the most recent scheme from my alphasyllabary (which is the I have been working on the most right now) then we could probably get by with just using 11 of the 16 available syllables from Silbo Gomera to spell out the words. There is one possible problem: Running out of breath whistling all the letters.
That is why I favor a written_syllable-to-whistled_syllable mapping in this case over a written_letter-to-whistled_syllable mapping.
To give you an example of how this would work, (if I remember correctly) one consonant of Silbo is tS, and there is a vowel i, so we can make the syllable [tSi]. That can be matched with any of the proposed syllabic "bins" for instance jo/ju/ta/ka. So if you accept that mapping (and there are hundreds if not thousands of acceptable mappings, so you can play around with them to get the melody you like), by whistling 'tSi' (with stress, and perhaps a pitch distinction, to mark the word boundary) you mean 'jo'. The one caveat is that you couldn't add new words because this scheme only works to pick out the word from the lexicon. Using the previous mapping, and adding another vowel I know is present in Silbo 'a' we can create the syllable tSa, we can use it with the "bin" pa/la; with these two syllables we can whistle the word tSatSitSa which can only
mean 'pakala' because how I've deliberately divided the syllables of TP among the "bins". Note: I suggest keeping the TP convention of stress on the first syllable because that will allow us to keep short words from gluing onto the end of longer words.
I almost forgot to mention, Busuu.com has recordings of Silbo. Busuu is free and totally worth signing up for that reason alone.
jan Kipo: I don't pretend to know how Silbo stacks up against Solresol, but I do know that its whistlers (according to studies!) break the language up into syllables with vowels and occlusions. Maybe you could learn it!
