How to Keep Time as You Read Sheet Music
Use Time Signatures to Count Beats With Musical Notation
May 16, 2009
When reading sheet music, a tune’s melody which is determined by where notes are placed on the musical staff, is important, but just as crucial is the song’s rhythm. Once musicians understand the basics of the musical staff and the key signature, they’re ready to tackle the next symbol to the right—the time signature.
How to Understand Time Signatures on Sheet Music
At the beginning of the musical staff, just to the right of the key signature, are two numbers arranged one on top of the other like a fraction. These numbers are the piece’s time signature and are important when it comes to understanding the song’s rhythm.
Read Sheet Music by Beats per Measure
The top number in the time signature lets musicians know how many beats are in each measure. Measures divide the staff into sections. They are marked out with vertical bar lines perpendicular to the five lines of the musical staff.
It’s important to know how many beats each measure gets and where each new measure begins because the first note usually receives more of an emphasis.
Four is the number most commonly found on the top of a time signature. To see how four beats per measure effects the beat, musicians can count to four several times and clap on each beat. A heavier accent naturally falls on the number one each time it comes around. They can experiment with less common time signatures by counting to three, or just to two several times as well. When played or sung, each rhythm lends the music a different feel. Waltzes for example, all have the characteristic “1, 2, 3, 1, 2, 3…” rhythm that comes with three beats a measure.
Notes and Their Value in Sheet Music
The bottom number of the time signature determines which note equals one beat. By far, 4/4 time is most common meaning each quarter note receives one beat. There are less common time signatures which shift the value of notes. A two in the lower part of the time signature for example, designates the half note as getting one beat. An eight as the bottom number means the eighth note receives one beat. This shift affects the values of all the other notes as well.
While becoming familiar with the value for each note and rest, beginners should focus on simple sheet music which will most likely have either a 4/4, 2/4, or 3/4 time signature.
Once musicians are comfortable with the basics of the staff, clef, key signature, and time signature, they’re ready to get started. All they need is an understanding of the notes and rests they’ll encounter along the staff.
