What do the tempo words mean?
The words are Italian, from the centuries when Italian was the language of printed music, and every country still uses them. Each names a mood as much as a speed: andante is "walking", allegro "cheerful". The numbers beside them are the ranges metronome tables usually give, a convention that varies from one edition to the next rather than a definition.
| Term | Meaning | About (BPM) |
|---|---|---|
| Grave | Very slow and solemn | 30–39 |
| Largo | Broad, very slow | 40–59 |
| Larghetto | A little less slow than largo | 60–65 |
| Adagio | Slow, at ease | 66–75 |
| Andante | At a walking pace | 76–107 |
| Moderato | Moderate | 108–119 |
| Allegro | Fast and bright | 120–155 |
| Vivace | Lively and quick | 156–175 |
| Presto | Very fast | 176–199 |
| Prestissimo | Extremely fast | 200–250 |
How do you read ♩ = 120?
A metronome mark gives the speed exactly: the note shown, so many to the minute. ♩ = 120 means 120 quarter notes a minute, two every second. In 6/8 the mark is usually written with a dotted quarter, such as ♩. = 60, because that is the beat the music is felt in.
Slowing down and speeding up
Inside a piece the tempo can bend. rit. (ritardando) and rall. (rallentando) both mean gradually slower, accel. (accelerando) gradually faster, and a tempo returns to the speed before the change. A fermata (𝄐) over a note holds it longer than written, for as long as the moment needs.
