Mannish Boy — Muddy Waters (1955)

A whole song built on one chord. What organises the time here is not the harmony: it is a short figure that repeats, and the gaps it leaves when it stops.

Why this song

Put it on and count the chords. You will finish the song having counted one.

That is the question this record answers: how little do you need before something is music rather than an exercise. One chord, as long as something else is moving.

Muddy Waters made it in Chicago in 1955, and the figure he used has been travelling ever since. George Thorogood borrowed the hook and part of the words for Bad to the Bone in 1982. That riff is seventy years old and still in circulation.

Historical context

Muddy Waters was born McKinley Morganfield and grew up on a Mississippi plantation, playing guitar at country parties. In 1943 he moved to Chicago, like millions of Black Americans in those years.

The blues changed there, for a practical reason. Chicago clubs were loud and crowded. He put it like this: "When I went into the clubs, the first thing I wanted was an amplifier. Couldn't nobody hear you with an acoustic."

In 1944 he bought his first electric guitar and put together his first electric band. That decision — taken to be heard, not to invent anything — is where Chicago blues comes from: country blues run through loudspeakers.

This is the Chess Records building, the label that released the song. Chess moved in here in May 1957, so Mannish Boy, recorded in 1955, was not made in this room. It is a museum now.

The song did not appear out of nowhere. In 1954 Muddy recorded Hoochie Coochie Man, built on a figure that kept stopping dead. In March 1955 Bo Diddley took that figure for I'm a Man.

Two months later Muddy answered back with this one, calling "boy" a musician more than ten years younger than him. All three are relatives, and both Muddy and Bo Diddley are credited as writers of Mannish Boy.

Musical characteristics

Listen to the opening. A short figure plays, everything stops, the voice carries on alone, and the figure comes back. Again and again, to the end.

That short repeated figure you recognise instantly is a riff. What is odd about this one is that it accompanies nothing: it is the skeleton. With no chord changes and no chorus coming, the only thing telling you where you are is how many times the riff has gone round. The riff is doing the job of form.

The gaps matter as much as the notes. The band hits, stops dead, and leaves the voice alone in the silence. It sounds as if the music has slowed down, but the pulse never moves: when they come back in, they come back exactly on time. That device is called stop-time.

There is one chord, and it is not just any chord. It is A7: an A major with an extra note that does not quite fit and leaves the feeling that something is still waiting to resolve. Since it never resolves, the tension never goes away. That extra note is the seventh, and it is the basic colour of the blues.

On top of all that there is a harmonica. In Chicago the harmonica stopped sounding rural because players cupped it against a cheap microphone and pushed the amplifier into distortion. It comes out thick and dirty, closer to a broken saxophone than to a pocket instrument.

Hard facts: A major over an A7 chord, 4/4, 72 BPM, 2:55. The form is the riff and its stops, repeated, with no chorus and no bridge.

Trivia and curiosities

  • Muddy's regular harmonica player was Little Walter, but he was on tour with his own number one, My Babe, and could not make the session. Junior Wells played instead. It is the only Muddy Waters recording between 1953 and 1957 without Little Walter, and it happens to be the famous one.
  • The lyric spells the word out: "I'm a man, M, A, child, N." It sounds like bragging, but in the American South a grown Black man was called "boy". Spelling that word into a microphone in 1955 was saying something else.
  • Three names sign the song: Muddy Waters, Mel London and Bo Diddley. The writer of the song this one answers ended up being paid by it. When two songs are this close, the argument ends at the copyright office, not on stage.
  • Bad to the Bone (1982) adapts the hook and the words of this one. Its video stars George Thorogood playing pool against Bo Diddley, appearing as himself. A fairly open loan, with the lender as a guest.
  • The famous version is not the 1955 one. In 1977, well past sixty, Muddy recorded it again with Johnny Winter for the album Hard Again. That is the take used in Goodfellas and in a Levi's advert, and the one that in 1988 gave him his only appearance in the UK charts, thirty-three years later. Which recording becomes "the" recording gets decided long after the session.

Classroom activities

  • Play: the class chart is in C and it is one chord. Ukulele and guitar can take the riff together. There is no chord change to get wrong: the hard part is starting and stopping in the same place.
  • The stop experiment: play it through twice. First with the stop-time gaps. Then fill the gaps, with the backing sounding all the way through. Ask the class which version sounds bigger, and why.
  • Analyse: a closed question. If the harmony never changes, how do you know a new section has started? Listen to a long stretch and write down what changes each time (who plays, who drops out, what the voice does).
  • Create: pick one chord, just one, and invent a two-bar figure with a silence in it. Repeat it and build a minute of music by changing only who plays on each time round. Steal the procedure, not the song.

In the theory and history book — this song fits ¿Cómo sabes por dónde vas en una música que oyes por primera vez?, because here the form is not marked by the harmony, and ¿Cómo se guarda algo que solo existe mientras suena?: without the Chess records, this blues never leaves Chicago.

About the chart — there is no ukulele part for this song in JamZone. It has bass, drums, guitar and keyboard, and nothing else, so do not go looking. For the ukulele, use the tutorial below.

Official audio — Muddy Waters' official channel. Nobody made music videos in 1955. Also, this recording is not the 1955 one: it is the 1977 remake, nearly twice as long and with the full band. It is the one most people carry in their heads.

Guitar tutorial — Marcos García, in Spanish, aimed at beginners and with the tab on screen.

Ukulele tutorial — TenThumbs Productions. He gets the riff onto the ukulele, which is exactly what the chart is missing.

Bass tutorial — Bradley Fish, three minutes for beginners. He teaches this figure next to the Bad to the Bone one, which is its child.

Drums — Drumscribe. Not a spoken lesson: the drum score scrolls past in time with the song.
