Is tempo affected by the Doppler effect ? for ex: would the beat of music be changed as the source approaches or recedes from the observer?

Absolutely. The tempo would speed up as the source approaches you.

Dr. Bradburn

Yes. It's just like spinning a record (remember records?) faster on the turntable.

Tim Mooney

Yes, in the same way and for the same reason that the pitch is affected, the tempo is also affected. If the source of music moves away from the listener, the beat appears to go slower then when the source of the music moves away.
