Google’s venerable (and profitable) search engine is well known for offering useful tools beyond its core functionality, and Microsoft has been tricking out Bing with a few extra features of its own — such as an app for tuning your guitar right from the search page. Here’s how to make sure you’re playing in tune using Microsoft’s search engine.
As with Google, the trick is inputting the right query: in this case you need to type "guitar tuner" into Bing, and hey presto, that's exactly what you get. Choose your tuning option from the drop-down list at the top of the dialog box and then click on any note to hear it. If you're on a laptop, phone or tablet and have internet access, you'll never be out of tune again.
If you want to keep time more accurately, you can also try searching "metronome." When the tool pops up, set your parameters accordingly then click Start to hear it. Microsoft says the two tools were written by interns working on Bing over the summer months, and they're both features that the mighty Google doesn't offer (at least not yet).
