Students of music,
Making mashups is not easy, but the end result can be very, very cool.
Remember the basic rules:
1) The two songs have to be in the same tempo
2) The two songs have to be in the same meter
We listened to two examples (Radiohead with Dave Brubeck and James Brown with The Beatles)
If you use your BIG6 research skills, you can probably find a good tutorial to help you.
You can also find song banks listing songs with the same BPM (beats per minute)/tempo.
Good luck mashing up!
