When you’re focused on your bowing, your fingering, all the little details you have to think about as you perform, other performance details can get lost. Recording yourself as you play is an effective way to listen and observe your performance from the outside.
If your goal is to improve your tone, audio recordings are sufficient. You can record yourself as you practice at home or in other informal settings. If your goal is to enhance your stage presence or get a closer look at what you’re doing physically as you play, then you’ll need a video recording, of course.
First, be realistic. You’re not recording in a professional recording studio. You can record at home in front of your computer. However, you still want to capture the best sound, so you have a clear understanding of the tones you’re producing and where you may need work.
There are two points in which you can maximize the quality of your recording. First, at the time of recording and second, by editing out background noises after the fact. If you want to record yourself often, invest in a USB microphone that plugs into your computer or phone. Using a high-quality microphone will go a long way to improving your recorded sound quality. Prices range anywhere from $10 to $200.
Also, consider where and when you're doing the recording. Your bedroom may be okay. It's probably better than recording outside. If you have access to a soundproof room, even better. If you aren’t recording in a soundproof room, here are a few tips to improve your acoustics:
To edit your recordings, you’ll need editing software (or a “DAW” – digital audio workstation, if you want to know the lingo). Most computers come with audio recording applications that have many useful tools. Microsoft has Sound Editor and Apple has GarageBand. You can also find plenty of apps for your phone that both record and provide editing tools. Two caveats regarding editing:
Editing software isn't strictly necessary, but a useful extra. To benefit from reviewing practice recordings immediately, get the best USB microphone you can find in your price range and start recording. If you want to set up a nice at-home recording studio, you can find detailed lists of equipment needed, depending on how sophisticated you want your home studio to be.
You can use your computer or phone camera to get an acceptable video with these tips:
Video recording your practices will do more than help you perfect your technique and stage performance. It is also good experience for when it comes time to put together an audition video.
You spend a lot of time practicing. Get the most out of your efforts by recording many of your sessions. You can review them and ask your teacher to review them as well. If you record yourself playing the same piece over time, you should hopefully see some quantifiable improvement. There’s no reason not to use this ubiquitous technology to improve your playing.
