Johnston–Copper notation: Difference between revisions

Line 10:

An example from Johnston shows the use of a form of a 'neutral' sign. [[Johnston Quartet 4 -01]] and an example from Copper shows the same usage with a somewhat altered symbol.

In Johnston's hand-engraved score the neutral sign looks somewhat like a thick dash or hyphen; in Copper's notation, made with the Score computer engraving program ( [[scor4]]) , it is an arrow with a flag at the top (used for the 'down one comma' neutral indication). Both are used for exactly the same purpose: in C major, Johnston's score, the note D if unaltered would sound too high, since it is tuned by default as a perfect fifth above the G according to the three 4:5:6 chords. in beginning as he does, he wants the D to be tuned lower and in fact, tuned exactly to the open D string. In D major, Copper's score, the equivalent note is an E , a perfect fifth above the A according to the same three 4:5:6 chords in D major; and for the same reason, the note E if unaltered would sound too high in bar 3 if not altered down by a comma. This gives a first orientation toward understanding how ~~Johnson~~'s notation is modified by Johnston-Copper notation: the addition of a key signature changes which notes need alteration. Copper's notation in C major is identical to Johnston's, with the minor difference of symbol designs.
