I have been reading up on this topic and there is a condition called
amusia which my father possibly had. It would explain why seemed to always classify music as 'racket' - to him music was just noise.
As far as my lack of music ability goes I know
1) I can't tell if an instrument is out of tune
2) I can't sing in tune
3) I often cannot tell what instrument is being played.
Yesterday I talked about this with a friend. She said after that the instruments I seem to like are the strings and the flute. She based this on the insrtumental pieces I said I liked - I believed I mentioned
In the Hall of the Mountain King,
Morning Mood, as well as
The King of the Golden Hall (from the Two Towers) and the theme music from
Game of Thrones). She also added that this might also be the reason I seem to like Celtic music more than some other type of music, for example, I love the Dubliner's version of
Carrickfergus.
