It's no secret that virtually everyone loves music in some form or other. After all, music is the universal language. In one way or another we all participate in it from our cradle song to our wedding song to our funeral song, with thousands of other s stops along the way.

The country-western fan may not like jazz, but he or she sure loves the sound of pickin' & grinnin'.

And that's as it should be. If we all liked the same kind of music, there just wouldn't be the variety that is available to us now. We can choose from musical styles ranging from heavy classical and opera to rock to children's songs to Broadway musicals to gospel music to the blues.

Each has its place, and each seems on the surface to be drastically different than another form of music. The key word is "on the surface." But beneath the surface of all music is a commonality that is organic to all forms and styles of music.

So what does all music have in common? What makes music tick?

At least 3 things – sometimes more, but never less:

1. Melody

2. Rhythm

3. Harmony

The melody is the part of a song or composition that you whistle or hum – in other words, the tune of the song. In one sense, it is the most visible of the 3 elements, because melody is what identifies a song. Without melody, it would be difficult to even conceive of a song or piece.

In musical notation, the melody is almost always written in the treble clef – also known as the treble staff. It consists of a horizontal line of notes that move up and down on the clef as the tune moves higher or lower.

Rhythm is the beat – the swing – the throb of the music. It happens in repeating patterns, depending upon the type of music. It is like a horizontal line of beats which occur at regular or semi-regular intervals. A waltz, for example, basically consists of a heavy beat followed by two lighter beats. So we say that a waltz is in triple meter – one strong beat followed by two weak beats, then repeated.

A march, on the other hand, generally consists of a heavy beat followed by a light beat, then another heavy beat followed by another light beat. (I'm simplifying, of course – there are many varieties... ) So a march is in duple meter – as you might expect since we have two feet and we march in left-right-left-right patterns.

All rhythms are some combination of triple meter and/or duple meter, and the possibilities are endless – from boogie to R&B to mambos and sambas and bossa novas and... .on and on.

Harmony, the 3rd aspect of music, is the musical background of a song – the chords, or intervals "behind" the melody. Without harmony, a song sounds empty – like a vocalist singing without an accompanist – or accapella. Music doesn't HAVE to have harmony to function, but in actual practice it almost always does, even if it is just the interplay of two melodies, as in counterpoint.

You could spend a lifetime learning all the nuances of music, but it its most basic form, it is these 3 elements combined together; melody, rhythm, and harmony that comprise music.
