I am buying a music system that works on 110v -60HZ and taking it with me to India. India works on 220v – 50HZ. I can get a transformer that will step down my voltage from 220v to 110v. My question is about the frequency. Would my appliance still work as I will not be converting the frequency from 60 hz to 50 hz. If it does work, will it affect the quality of the output of my music system or the life of the equipment?
A stepdown transformer should be all you need, with the following caveats:

If the unit incorporates synchronous motors for a tape deck or turntable, they will run at 5/6 speed.

If the unit incorporates a digital synthesized tuner, the channel spacing and/or frequency coverage may not match the Indian broadcast allocations.

Running a 60 Hz power transformer on 50 Hz will generally cause the transformer to run a bit warmer than usual. Whjether this is a problem or not depends on the transformer design.
