To play music, you need to know its meter, the beat you use when dancing, clapping, or tapping your foot along with a song. When reading music, the meter is presented similar to a fraction, with a top number and a bottom number, we call this the song’s time signature. The top number tells you how many beats to a measure, the space of staff in between each vertical line (called a bar). The bottom number tells you the note value for a single beat, the pulse your foot taps along with while listening.
In the example above, the time signature is 4/4, meaning there are 4 beats per bar and that every quarter note gets one beat. Click here to listen to sheet music written in 4/4 time, and try counting along 1,2,3,4 – 1,2,3,4 with the beat numbers above.
In the example below, the time signature is 3/4, meaning there are 3 beats per bar and that every quarter note gets one beat.
Let’s look again at the above examples, notice that even though the 4/4 time signature in “Twinkle, Twinkle Little Star” calls for 4 beats per bar, there aren’t 4 notes in the second bar? That’s because you have two-quarter notes and one-half note, which added together equal 4 beats.
In addition to your note values and time signature, the last piece to feeling the rhythm is knowing your tempo or beats per minute. Tempo tells you how fast or slow a piece is intended to be played, and often is shown at the top of a piece of sheet music. A tempo of, say 60 BPM (beats per minute) would mean you’d play 60 of the signified notes every minute or a single note every second. Likewise, a tempo of 120 would double the speed at 2 notes every second. You may also see Italian words like “Largo,” “Allegro” or “Presto” at the top of your sheet music, which signifies common tempos. Musicians use a tool, called a metronome, to help them keep tempo while practicing a new piece.
At the Guitar Therapy lessons, I will be demonstrating the different time signature counts using a metronome so that my students will be able to master this crucial skill in no time.
