Given the first note solfeg identify the second notes solfeg syllable

High Sol

Explanation:

One way: You work your way up with your solfege. (like just going sol, la, ti, do all the way up to the next note)

Sencond way: you could start counting (numbers) from the space the first note is in all the way up to the next note. You'll notice it's just 8 and knowing that the solfege scale is by 8ths and so if you start on sol and its 4 lines and 4 spaces (incuding the starting space) then you will end on sol just it's an octave higher.

ive noticed that too but is this a question
