In notes of small denomination (eighths and smaller) this same
thing is often indicated by _stroking_ the stems together as
in Fig. 36. This can only be done in cases where the natural
grouping of notes in the measure will not be destroyed.

D. To mark special note-groups (triplets, etc.), in which case the slur
is accompanied by a figure indicating the number of notes in the group.
See Fig. 37 (_a_)

The most common of these irregular note-groups is the
_triplet_, which consists of three notes to be performed in
the time ordinarily given to two of the same value. Sometimes
the triplet consists of only two notes as in Fig. 37 (_b_). In
such a case the first two of the three notes composing the
triplet are considered to be tied.

[Illustration: Fig. 37.]

When the triplet form is perfectly obvious, the Fig. 3 (as
well as the slur) may be omitted.

Other examples of irregular note-groups, together with the
names commonly applied, follow.

56. The _combination of slur or tie and dots_ over the notes indicates
that the tones are to be somewhat detached, but not sharply so.
[Illustration]

This effect is sometimes erroneously termed _portamento_ (lit.
_carrying_), but this term is more properly reserved for an
entirely different effect, _viz._, when a singer, or player on
a stringed instrument, passes from a high tone to a low one
(or vice versa) touching lightly on some or all of the
diatonic tones between the two melody tones.

57. The horizontal _dash over a note_ [Illustration] indicates that the
tone is to be slightly accented, and sustained. This mark is also
sometimes used after a staccato passage to show that the tones are no
longer to be performed in detached fashion, but are to be sustained.
This latter use is especially common in music for stringed instruments.

58. The combination of _dash and dot over a note_ [Illustration]
indicates that the tone is to be slightly accented and separated from
its neighboring tones.

59. _Accent marks_ are made in a variety of fashions. The most common
forms follow. [horizontal accent symbol] [vertical accent symbol] _sf_
