Celtic Music (per Wikipedia)
Celtic music is a broad grouping of music genres that evolved out of the folk music traditions of the Celtic people of Western Europe. It refers to both orally-transmitted traditional music and recorded music and the styles vary considerably to include everything from “trad” (traditional) music to a wide range of hybrids.
It is common for the melodic line to move up and down the primary chords in many Celtic songs. There are a number of possible reasons for this:
- Melodic variation can be easily introduced. Melodic variation is widely used in Celtic music, especially by the pipes and harp.
- It is easier to anticipate the direction that the melody will take, so that harmony either composed or improvised can be introduced: cliched cadences that are essential for impromptu harmony are also more easily formed.
- The relatively wider tonal intervals in some songs make it possible for stress accents within the poetic line to be more in keeping with the local Celtic accent.
