How to make a song on your phone keypad? (how to make a song with keypad)

Wondering How to make a song on your phone keypad? If you are trying to make a unique sounding song then you have probably thought about what instruments you can incorporate into your track that you don’t hear every day. Not many people stop to think about it, but a simple phone keypad is an instrument in its own right, albeit a limited one.  

We decided to tackle the question of what notes you are actually playing when you sit down and noodle around on your phone, and boy is it a weird story. Basically you are playing 2 notes at once when you press a key on your keypad.

This leads to a deep rabbit hole to explain how computers were initially used to detect high (Binary 1) and low (Binary 0) signals in the modernized computer exchanges that have since come and (mostly) gone.

How many DTMF tones are there?

DTMF has 8 tones, but as we mentioned earlier, these are separated into high and low tones that a computer can translate into binary. So if each key has 2 tones, then we end up with 16 frequencies in total.

All you need to know is that these signals are called DTMF (Dual Tone Multi-Frequency) and they take a combination of 2 notes and basically add them together.

I’m not sure what you were expecting, but I thought that the sequence of notes was going to correspond with a scale, but this is a little different. I have put a table together that explains what each key produces, and what frequencies are added together to give us that tone.

Keypad Frequencies and Notes on your phone

What songs can you play on a keypad?

If you have ever been bored and started playing a little song on your phone with the keypad, then you are not alone. Many people have tried to get a song or two playing on their keypads.

Back in the late 90’s and early 2000’s it was actually a feature on some cell phones. You could record your own ring tones by using the keypad to punch in the notes of a song.

The reults would vary from person to person, and I can remember a friend helping me figure out Black Sabbath’s NIB on my Sony Eriscon so I could have a cool ring tone. Fun Times.

To answer the question of what song’s we can play on a phone’s keypad it must be said that you can actually play quite a lot.

Although the notes that are available to us are not chromatically sequential, ie , notes that play from a scale – but there is enough here for us to have a little fun.

How do you play Mary Had a Little Lamb on a phone keyboard?

Mary had a little lamb is one of those songs that your guitar teacher normally forces you to learn when you are just getting started out, so we can start with that song if you really want to. (I don’t know why you would, but hey, who am I to judge?)

Mary Had a Little Lamb on a keypad goes a little something like this:

6, 5, 4, 5, 6, 6, 6

5, 5, 5

6, #, #

6, 5, 4, 5, 6, 6, 6, 6, 5, 5, 6, 5, 4

Happy Birthday to you!

1, 1, 2, 1, 6, 3

1, 1, 2, 1, 9, 6

How can I play music on my phone?

It’s really easy! Simply open up your dialer on your phone and start tapping away. Then you need to make sure that you don’t press the green dial button either, otherwise you could accidentally call someone, and then play then happy birthday from your phone. Not ideal.

If you are looking for more musical territory to conquer on your phone then you should think about installing a piano app that lets you tickle the ivories at your leisure.
