Will I lose my music after canceling Apple Music?

I have just bought a new MacBook Air to replace an old Win 10 box. I took up the “3 month” Apple Music freebie as I have a ton of music in iTunes on the windows box ripped from CDs which I wanted to sync with the new MacBook. I don’t have any music purchased from the store on there, just the old CDs. Everything had synced to the new MacBook ok, but if I cancel apple music at the end of the 3 months will I lose all my newly synced music from the MacBook ?
