How to Change the Pitch of a Song

Ever tried to use a sample in a song you’re producing but the key doesn’t fit? Or sing a song but it was just out of your range? It’s time to use transposition to change the pitch of a song!

In production, singing, or playing an instrument, knowing what, why, and how to change the pitch of a song can make a world of difference and can be extremely helpful in your musical practice.

What is pitch?

In order to learn how to change the pitch of a song, we must first dive into what pitch actually is to begin with. Pitch is defined as the quality that makes it possible to judge a sound as ‘higher’ and ‘lower’ in association with musical melodies.

The frequencies of sound waves (created from vibrations) are measured in hertz or Hz. Humans can generally hear from 20Hz (low pitch) to 20,000 Hz (high pitch), whereas other animals (such as dogs, bats, dolphins, etc) can hear what we call Ultrasound, where it passes 20,000 hertz.

What is transposition?

When we move a collection of notes up or down in pitch, we are transposing. While transposing you are moving the notes up or down by semitones, which are the smallest interval between two notes and can also be referred to as a half step. This is important to know because if you want to transpose a song from one key to the next, you need to know if you need to pitch by 1 or 2 semitones.

Knowing all this can help you tremendously along your musical journey, because as mentioned at the beginning, if you have a song that you’re trying to sing along to or a project you’re producing with a sample in the wrong key, pitch-shifting is vital to crafting music to fit into what you need.

Quality of pitch-shifting

You might be wondering if your work will lose quality through the process of changing the pitch, and the answer is no! What CAN happen is that the song can begin to sound somewhat distorted.

Most software is very advanced and much better than what it used to be, but if you manipulate the song too much, it can cause sound distortion and sound like it’s lost some of its original quality. Still, you can attempt to save as much quality as possible by being sure to use high-quality audio files, and use files or samples with a high sample rate of 96kHz or more rather than the usual 44.1kHz or 48kHz.
