Remarks
Commonly also called a 'slide'. The term 'glissando' is frequently used to indicate
both
the case where distinct intermediate pitches are produced (as on the piano) and the
case
where they are not (as on the trombone), though the latter is sometimes referred to
as
'portamento'. The visual appearance of the indicating line may be recorded in the
lform and lwidth attributes. The starting point of the glissando may
be indicated by either a startid, tstamp, tstamp.ges, or
tstamp.real attribute, while the ending point may be recorded by either a
dur, dur.ges, endid, or tstamp2 attribute. It is
a semantic error not to specify one starting and one ending type of attribute.
