Traditional Irish music embraces a variety of tune types, each
with its own distinct features.
RHYTHM
Each dance tune has a specific "time signature" {number and
type of beats per musical bar}and its own rhythmic characteristics,
as follows:
The Dance Tunes
REEL - 4/4 (4 crotchets in every bar), accent/swing on the 2nd and
4th crotchet of each bar.
JIG - 6/8 (6 quavers in every bar), quavers grouped in two groups
of 3, accent on first quaver of each 3.
WALTZ - 3/4 (3 crotchets in every bar), accent on the first beat of
every bar.
POLKA - 2/4 (2 crotchets in every bar), accent/swing on the 2nd and
4th quaver of each bar.
HORNPIPE - 4/4 (4 crotchets in every bar) characterised by a
"dotted rhythm".
Differing from the dance tunes is the SLOW AIR . These are written
in a variety of time signatures but are played freely with "rubato"
[classical Italian term, meaning "borrowed time"]
Of course, the character of an individual tune is also influenced
by the tempo (speed) of its performance.
TONALITY
In addition to the Western standard major and minor scales, the style
of Irish music also employs the ancient modes, e.g. aeolian, dorian
etc, from which major and minor tonality developed. A tune may move
between tonalities e.g. with the 3rd and 7th notes of the scale often
altered at different points in the tune. Such an example could be
a tune with the first part in D major but the second part in D mixolydian
(flattened 7th).
