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.
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
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.
