In this lesson

A boy from New Orleans

Louis Armstrong was born in New Orleans, in about 1901. Nobody is sure of his exact birthday, because the records and his own stories do not agree. As a boy he first played the cornet, a close cousin of the trumpet.

Friends and fans called him "Satchmo" and "Pops". He played and sang for many years, and he died in New York City in 1971.

From New Orleans to Chicago

Jazz grew up in New Orleans in the late 1800s and early 1900s, the same city where Armstrong was born. It mixes blues, ragtime, marches and many rhythms.

In 1922, he moved to Chicago to play in King Oliver's band. A few years later he made records with his own group, the Hot Five, starting in 1925.

One story says that during the 1926 recording of Heebie Jeebies, his sheet music fell on the floor, so he made up silly sounds instead. People tell this story a lot, but nobody can be sure it happened exactly that way.

Making up music on the spot

Jazz is music where players often make up parts as they go. This is called improvising. It is a bit like telling a story out loud instead of reading it from a book: you choose the next words while you speak. Armstrong was famous for trumpet solos that sounded fresh and free.

Jazz also often has a bouncy feel called swing. Instead of playing two quick notes exactly the same length, the player makes the first one a little longer and the second a little shorter: long-short, long-short, like skipping. He also sang "scat", which means singing silly sounds like "ba-doo-bee" instead of words, so the voice works like an instrument.

Try listening for

These four recordings show different sides of Armstrong.

West End Blues, the start
Listen for the trumpet playing all alone at the beginning, with no steady drum beat yet.
West End Blues, the voice
Listen for Armstrong singing scat sounds, like a talk with the clarinet.
Heebie Jeebies
Listen for the silly made-up sounds he sings instead of words.
What a Wonderful World
Listen for his low, gentle singing and the slow, calm beat.

Listen to Heebie Jeebies and try singing your own silly sounds in the same rhythm. Then clap on every beat and see which sounds fit best.
