Tone
Two quotes contradict each other.
The initial syllable usually retained some degree of stress. In long words, especially recognized compounds, it was, though lower in tone, often equal in force to the main stress.
In Tarquesta pronunciation the highest tone-pitch also accompanies as a rule the main stress in words pronounced ‘normally’, sc. in isolation, or in circumstances where no special significant tonal modifications were required. An exception to this rule is provided by long words, especially compounds, in which a very strong secondary accent fell on the initial syllable, while the actual main stress fell later (often on a derivative syllable). In such cases the initial secondary was in normal circumstances higher in pitch than the succeeding main stress […]
The TQt. tonal range is large, and its verbal and sentence tone-patterns are numerous; while stress is not excessive, and the quality of unstressed vowels is clear and not obscured. […]
Even where a syllable that in the Primitive period bore the main accent now still bears a strong secondary stress that syllable as a rule is lower in tone than the main stress — except in the case observed above, of a strong secondary stress on an initial stem-syllable; but the high tone on the secondary in those cases is due not to ancient accent but to contemporary feeling for the special significance of the initial syllable.
Intonation in Questions
Questions appear in Q. to have had in colloquial speech the same form as statements, distinguished in tone only, not by word order.
While no indication is given about what kind of tone change is observed, since a neutral statement has a falling tone (cf. the recordings of the Namárie ), it’s natural to assume an opposing, rising tone in the questions.
Intonation on Emphatic Elements
[…] the object is usually placed after the verb, unless great emphasis is placed on it (not the case here), and even so that is more frequently shown by tone only.
This statement is somewhat confirmed with the recording of sí man i yulma nin enquantuva to be a rising tone.
