When practicing singing, I found myself naturally singing the number of the Key instead of the Solfege. So for example singing London Bridges Falling Down was
5 6 5 4 3 4 5 . . . vs Sol La Sol Fa Mi Fa Sol
In this I show both the Solfege and the numbers to make it clear what I'm asking.
So, Is there a benefit to using the Solfege names vs just singing the numbers?
I didn't find anything on MT&P (Stack Exchange Music Theory & Practice), but did find this on Redit:
Several answers were given, the one I liked was:
For me, solfege syllables make it easier to hear/sing flats and sharps. E.g., "do - re - me" instead of "do - re - mi" for minor versus major third. If you're doing numbers you'd have to sing the same syllable for the major versus minor pitch and it's harder to make that association / differentiate between the two. Unless you're differentiating somehow?
I'm asking the question here since this is where I go for answers to music questions. :-)
