It normally requires a bipolar powersupply (a positive and negative supply) which may be a problem. It's also not especially fast or quiet (low noise). If these things are not problems, you're on the right track. If they might be, I'd suggest an LM833 which is a low noise op-amp specifically designed for audio use. Any electronics distributor (either local, or mail order i.e. Digi Key) should have them. If you need single supply operation, an LM324 would give about the same performance as the LM741.
