I sing a song which is partly in Scots Galic - I think - and the second verse is

Thou are the music of my heart
Harp of joy 'cruit mo chridh'
Moon of guidance by night
Strength and light thou are to me

It has a note to myself 'cruish ma chree'- I must have either found the words on a record sleeve or seen the phrase written.

I understood that the meaning was difficult to render into English even though we have the term heart strings this is something like 'harping of my heart'
