ether the foreign tone is actually
used for ornamental purposes as a _chromatic_, or to effect a
modulation. Thus _e.g._, "F[sharp] is the _intermediate tone_ between F
and G in the key of C."

_Clavichord_--an instrument with keys, resembling the square piano in
appearance. The tone was produced by forcing wedge-shaped pieces of
metal against the strings, thus setting them in vibration. The
_clavichord_ was one of the immediate predecessors of the piano, much of
the music written by Bach being composed for it, although this music is
now played on the modern piano.

_Colla voce_--with the voice: _i.e._, play the accompaniment according
to the soloist's performance rather than strictly according to the
rhythm indicated in the score.

_Colla parte_--same as _colla voce_.

_Coloratura_--florid passages in singing. Also applied to the style of
singing employed in rendering such passages. (See p. 76, Sec. 171.)

_Consonance_--A combination of tones agreeable to the ear and requiring
no resolution to other tone-combinations in order to give the effect of
finality. The major triad C--E--G is an example of a consonant chord.

_Contralto_--same as _alto_.

_Con variazioni_--with variations.

_Direct_--a sign ([direct symbol]) placed at the end of the last staff
on a page, to indicate what the first note on the next page is going to
be. This sign is now practically obsolete.

_Dirge_--a funeral chant. The dirge is named from the first word of a
chant used in the "office for the dead," which begins--_Dirige Domine,
Deus meus, in conspectu tuo viam meam_ (Direct, O Lord, My God, my way
in Thy sight).

_Discord_--an ugly, unharmonious combination of tones.

_Dissonance_--a harmonic combination of tones giving rise to the feeling
of incompleteness or unrest, and therefore requiring resolution to some
other combination which has an agreeable or final feeling. (cf.
consonance.) The diminished triad C--E[flat]--G[flat] is an example of a
dissonant chord.

_Divisi_--divided. An indication showing that the first violins, or the
sopranos, or any other body of performers ordinarily sounding in unison
are now to divide into two or more parts.

_Duet_--a composition for two performers. (From the It. word
_due_--two.)

_Ecole_--a school or style of composition or performance.

_Etude_--a study. Also an instrumental composition in the style of a
study, but intended for artistic performance.

_Euphony_--agreeable tone combin
