1. vocal or instrumental sounds (or both) combined in such a way as to produce beauty of form, harmony, and expression of emotion..
But music is not just this: since I was little I have spent a lot of time listening to it:
while I tidy up the house, while I work on my projects, while I'm on the train and when I'm with friends.
For each day based on how I feel I have a perfect song: if I'm sad I will listen to sad songs or happy songs
to cheer me up, and if I'm happy I will definitely listen to happy songs for example.
In short, my habits and all my days depend on the music I listen to, and the music I listen to depends on these.
