Some of the most annoying problems you can encounter when recording concern pitch. Obviously you’ll need all instruments you use to be in tune as much as possible, and in tune with each other, and your best point of reference is a tuner.
You’ll find that humidity and temperature can cause tuning problems, so it’s often best to retune every few minutes or even between takes. This will also give you enough consistency when compiling the best performance from different takes.
Some DAWs include handy tuner plug-ins, so check in with yours before shelling out for a hardware model.
