It Don't Mean A Thing If It Ain't Got That Swing
Fraser MacPherson Lyrics

It don't mean a thing
The worth or value of something is insignificant if a certain characteristic is missing.

If it ain't got that swing
This characteristic that is crucial to the value of something is a rhythmic quality called 'swing'.

(doo wah, doo wah, doo wah, doo wah Doo wah, doo wah, doo wah, doo wah)
These nonsense syllables are used to imitate the sound of swing music and to create an energetic atmosphere.

It don't mean a thing
As mentioned before, the worth or value of something is insignificant without swing.

All you got to do is sing
The act of singing is a way to add more swing to a piece of music and increase its value.

(doo wah, doo wah, doo wah, doo wah Doo wah, doo wah, doo wah, doo wah)
Once again, these syllables are used for emphasis and to create a lively atmosphere.

It makes no diff'rence
Whether a piece of music is slow and sweet or fast and hot, swing is the key factor that gives it worth.

If it's sweet or hot
The style or tempo of a piece of music is irrelevant when compared to swing.

Just give that rhythm
The most important thing to focus on is the rhythm, or swing, of the music.

Ev'rything you got
Put all your energy and effort into the rhythm to make it swing as much as possible.

Oh, it don't mean a thing
Once again, without swing, the worth or value of something is insignificant.

If it ain't got that swing
This final line emphasizes the importance of swing in music and how it is the defining factor in the value or worth of a piece.

(doo wah, doo wah, doo wah, doo wah Doo wah, doo wah, doo wah, doo wah)
The song ends with these emphatic syllables to leave a lasting impact on the listener and remind them of the importance of swing in music.
