Tempo

arts Maturity 11-13 Next article →

Tempo is the speed or pace of a piece of music.

It is also called the pulse of the music. This pulse helps create the atmosphere of a song. A fast tempo might feel bright or happy. A slow tempo can feel solemn or calm. Tempo is one of three things that create musical texture. The other two parts are meter and articulation. Meter uses a time signature to group notes. Articulation tells a musician how to play each note.

Musicians measure tempo using beats per minute, or BPM.

This tells you how many beats happen in one minute. For example, 60 BPM means one beat every second. A tempo of 120 BPM is twice as fast. This means there are two beats every second. Some people also measure tempo in measures per minute. This is common in ballroom dance music. In modern electronic dance music, knowing the BPM is very important. DJs use this to match the beats of different songs.

Measuring tempo became popular in the early 19th century.

This happened after Johann Nepomuk Maelzel invented the metronome. The famous composer Ludwig van Beethoven was one of the first to use it. In the 1810s, he included metronome marks for his eight symphonies. Before this, musicians used different ways to find the speed. During the Renaissance period, they used something called the tactus. This was a steady pulse like a human heartbeat. Today, music sequencers use the BPM system to be very precise.

Many musicians use Italian words to describe tempo.

This tradition began in the 17th and 18th centuries. At that time, most composers used Italian. Some common words include Allegro, which means cheerful. Andante means a walking pace. Presto means very quickly. Some words also describe a mood or feeling. For example, the word agitato means agitated. George Gershwin used this in his piano concerto in F. Other composers used French or German words too. For instance, German composers might use the word schnell for fast.

Different leaders help groups keep the same tempo.

In an orchestra, the conductor usually sets the pace. In a marching band, a drum major leads the group. In a popular band, the drummer or bandleader might choose it. Sometimes a singer starts a song alone. The speed they choose sets the pace for the whole group. Musicians can also use tempo rubato to change the speed slightly. This means the tempo is flexible rather than perfectly steady. It allows performers to show their own unique style.
