There are difficulties inherent in playing with any recorded accompaniment. Keeping the beat together is the most obvious problem. Recorded accompaniments, while providing a steady pulse just like a metronome, often makes the pulse harder to perceive than it is on a metronome. In a live ensemble, other players will automatically adjust their tempo to fit with yours, something that a recording cannot do. This puts the burden of adjusting tempo squarely on your shoulders when playing along with a recording. Likewise, a recording cannot react to any other nuance in your playing. Ideally, a performance with other players should be a dialogue, but the recording may make it seem more like a monologue.
Even so, a recorded playing partner can be better than no playing partner at all. Just being able to hear how the music fits together will make you better prepared to play with other people when this pandemic crisis is finally over. Let’s hope that occurs safely, if not soon.
