Are there any songs left to write?

We’ve probably all wondered this at some point or other. You turn on the radio and it’s yet another song that sounds much like one you’ve heard before.

So, are there any songs left to write? Let’s get straight to the maths…

A one-bar composition

First of all, let’s take one octave of the C major scale: C, D, E, F, G, A, B & C; the final C being one octave higher than the first.

Next, let’s take a bar of 8th notes:

8th notes

At the moment these notes are all Gs.

Now let’s see how many different melodies we could compose within this one bar, using just our eight notes from the C major scale.

The first note could be one of eight notes (C, D, E, F, G, A, B or C).

calculating possible melodiesThe second note could also be one of these eight notes. So that means there are 8 x 8 = 64 possibilities for the first two notes.

Note three brings another 8 possibilities so that means there are 8 x 8 x 8 = 512 possible three-note melodies.

Note four, brings the total to 4096.

That’s quite a lot of different melodies already. And we’re only halfway…

Let’s cut to the chase. The number of possible 8th note melodies in a single bar of C major is:

8 x 8 x 8 x 8 x 8 x 8 x 8 x 8 = 16,777,216

That’s over 16 million of them.

If each one of those melodies was 5 seconds long, it would take nearly 100 years of solid listening to hear them – not including toilet breaks.

Now let’s consider what we’ve left out…

The other five notes

Nobody says you can only compose a melody using just one scale. We still have the notes Db Eb Gb Ab & Bb available. So let’s add those into our sums.

With 13 notes instead of 8, my calculator tells me we would have this many possible 8-note melodies:

That’s over 815 million of them.

But wait, there’s more…

Harmony

The overall effect of each of those notes is different depending on the chord that’s played underneath it.

Sing the notes C and then E over a C major chord, and then over an Am chord and the difference between them is obvious.

And that’s just two of the many chords out there.

Other octaves

Why limit ourselves to one octave? There are plenty of melodies that go beyond this. Frank Sinatra’s recording of New York New York, for example, uses an octave and a half.

Rhythm

Why stop at 8th notes? We can have 16th notes, quarter notes, half-notes, 8th note triplets, 16th note triplets, rests, etc.

By the way, if you haven’t yet learned to read rhythms, I recommend working through the book Modern Reading Text in 4/4 by Louis Bellson.

Mind-boggling numbers

I’m not even going to try to work out how many one-bar melodies we could now have. We can see it’s an enormous number though. And we haven’t even considered song lyrics!

Songwriter - how many songs left to write?So why are there so many similar sounding songs?

Probably it’s to do with balancing the familiar with the original.

It’s easy to compose something original. Just detune your guitar and play a load of random notes and rhythms.

The chances are that you’ve just created a melody that you’ve never heard before; quite possibly one that nobody has ever heard before.

But most people probably wouldn’t like it.

That doesn’t mean it’s necessarily bad, but unless the listener is remarkably open-minded, it’s likely to be too original (i.e. too unfamiliar) for them.

Most of us humans like music that’s fairly familiar. We can make sense of major and minor scales, and mostly consonant harmony. We can understand logical chord progressions that ‘go’ somewhere, like Dm7 G7 C.

A little bit of the unexpected thrown into a song can be great too (we’ve all heard the words “I love that bit where it goes…”). But for the most part, mainstream popular music is built around well-established musical traditions that evolve quite slowly over time.

Conclusion

In conclusion, if you’re a songwriter and you’re wondering if there are any songs left to write, relax.

There are probably more songs waiting to be written than there are grains of sand on the planet.

Maybe just try to find the right balance between the overly familiar (cliché) and extreme originality (confusing!).

And if you do find yourself always gravitating towards the same old chord progressions, melodies and rhythms, well… why not just learn a bit more about chord progressions, melodies and rhythms?
