Part 2. What is Pitch?
When you listen to a melody, what makes one note sound high and another sound low? That's pitch. It comes from the frequency of sound waves, measured in Hertz(Hz).
Human ears usually pick up sounds between 20 Hz(very low) and 20,000 Hz(very high). Some animals — like dogs, bats, or dolphins — can hear even higher frequencies beyond our range.
In music, changing pitch means shifting notes up or down. This process is called transposition. The smallest step between two notes is a semitone.
For example, if a song feels too high to sing comfortably, you can lower it by one or two semitones to match your voice.
Why adjust pitch?
● Singing comfort: Bring a song into a key that suits your voice.
● Covers and remixes: Give a track a fresh feel by moving it up or down in key.
● Practice: Train your ear and improve range by singing in different pitches.
● Creative effect: Change vocal pitch to sound higher, lower, or even like another character.
Part 3. Customising Pitch for Song Creation with AI
Changing the pitch of an existing song works well if you just want to sing more comfortably or prepare a quick cover.
But what if you're not only adjusting - you're actually creating? For songwriters, producers, or even hobbyists who want to build music from scratch and set pitch exactly where they want it, AI music generators offer more freedom.
This is where Musicful comes in. It's a full AI music creation platform. You can start with a lyric, a short description, or even a humming track, and it will generate a complete song in the style you choose. Pitch adjustments can be part of the process, so the final track matches your exact vision.

How to Customise Pitch with Musicful?
Step 1. Open Lyrics Mode in Musicful.
Step 2. Paste your lyrics, and mark pitch changes with [ ].
For example, if you want the chorus to soar higher and the verses to stay mellow, you can write:
[Verse -2] The road feels heavy, shadows on my way
[Verse -2] I keep on walking, waiting for the day
[Chorus +3] Lift me higher, let the fire take control
[Chorus +3] Every heartbeat, every dream inside my soul
? Here:
● [Verse -2] lowers the verse by two semitones, making it deeper and easier to sing.
● [Chorus +3] raises the chorus by three semitones, giving it energy and lift.
Step 3. Choose your model(V1.5X or V2.0X for long tracks).
Step 4. Generate, preview, and export your song with the pitch exactly where you want it.
