I saw this question posted on a guitar site and I thought I would try to answer it. I’ve been playing in bands for so long that I don’t even think about it, but it definitely is a learned skill. One of the key skills needed to play with others in a band (or with backing tracks) is to play in tempo. Tempo is the timing of the song, the beat, the speed of the rhythm, how fast you want to tap your foot while listening to the song. If you are practicing by yourself, you tend to focus on the notes and sound of the riff… getting your hands into position to play that goofy chord. Tempo doesn’t feel that important by yourself….it sounds good to you. But as soon as you play with one other person…tempo is the guide that allows musicians to play together without staring at each other’s hands and instruments…trying to guess when they are going to play the next note.
The first thing to know about playing along with others is how to count music rhythm. Learn to count the beats and follow along with the sheet music while listening to the recorded version of the song. The lyrics of the song are a good hint at where you are, but are very difficult to use as a beat counter because they are so ‘free form’. The drums are the first place to listen when determining the speed of the song. Kick – Snare – Kick – Snare – Kick – Snare – Kick – Snare. That’s the simplest drum beat in rock. Each drum hit is played on a beat and there are usually 4 beats in a measure (look at the rock sheet music). Count them 1 2 3 4, Kick—Snare – Kick – Snare. The first thing I’d recommend to playing along with the Backing Tracks is to learn to follow along with the sheet music while listening to the recorded song. Practice playing along with the original recorded song. Work hard to stay in time with the song. If the song is too fast for you… turn the song off and practice the tough parts slowly until you can play it as fast as the original. Now that last sentence took 2 seconds to write, but can take weeks or months or even years to implement. I still can’t play Eruption as well as I’d like to…and I’ve only been practicing that for 20 years. When you can play along with the original song, then you can start with the Backing Track. That’s when it gets very rewarding!! Because the guitar you hear is all you and it sounds like the record. Pat yourself on the back, you just filled in for the rock star on the record.
Keep practicing!!
