(Table 10)

10.1. When, during the course of a measure, two or more simultaneous parts cannot be written as intervals with moving notes, they are written in succession and joined, without intervening spaces, by the sign <> (called in consequence the "in-accord" sign). The octave must always be marked for the first note after this sign, and it must also be marked at the beginning of a measure following one in which the in-accord sign has been used, even if this latter measure contains no in-accord sign.

Example 10.1-1.


.>"HFI'(<>V"DI "G&=(GFE<>"E'YJ!)


10.2. The order in which the parts are written is governed by the same general principles as those followed for the writing of intervals, the treble and bass being given priority whenever possible (see Par. 8.2).

10.3. It frequently happens that a measure is too long or too complicated for this simple use of the in-accord sign and it is then advisable to divide such a measure into convenient sections, each section being treated as an isolated unit of the measure. The sign used for this purpose is .K and it joins the sections on either side without intervening spaces. The in-accord sign used in such part-measure sections is changed to "1 and the first note after both signs must have an octave mark.

10.4. When either the in-accord or measure-division sign occurs at the end of a line the music hyphen should not be used.


Example 10.4-1.





10.5. The signs <> , .K and "1 can be combined in the following manner:

Example 10.5-1.



10.6. Accidentals preceding an in-accord sign do not affect notes in the same measure written after the in-accord sign.

Example 10.6-1.



10.6.1. (11-97) The use of the in-accord sign, however, often requires the re-marking of accidentals to avoid possible errors in reading. Such added accidentals should be preceded by dot 5.


Example 10.6.1-1.
