# Arthur Somervell: 1000 Exercises - Meaning of this notation

Arthur Somervell's uses the following notation on his One Thousand Exercises

Is it a standard notation? What's the meaning?

• Just a guess: all the letters are the first letters of the solfege syllables, do re mi fa sol la ti, so perhaps that’s what the letters refer to at least. Apr 6 '19 at 19:39
• I was thinking about it. Maybe it's 2/4 time signature and d' is do sharp

This is called the "tonic sol–fa" system. Created by a guy named John Curwen, it's not exactly a singing system like solfège, but rather a notation system.

At the risk of publicizing myself, I asked (and subsequently answered) a question on this exact distinction at What exactly is the "tonic sol–fa" system, and how is it different from solfège?

This standard solfege notation in certain English songbook editions: the letters are abbreviations of the doremi syllables.

There are also symbols for the note length.

I have to assume:

: = next beat. - = tied quarter

d’ = do hihgher octave

t, = lower ti
