Pitch Changer for Pianists

A pitch changer (or pitch shifter) raises or lowers the pitch of a song without changing its speed. For a pianist it's a practice essential: transpose a piece into an easier key for your hands, drop a song into a singer's range to accompany them, or shift a recording so you can play along without rewriting the sheet music.

Upload the song to KeyPitch and drag the Speed slider down — the track plays slower while the pitch stays exactly the same, so every note of a fast run or a tricky passage is easy to hear and copy. Start slow, get both hands clean, then push the speed back up bit by bit until you can play it at full tempo. You can also do this live on a YouTube piano lesson with the free Chrome extension.

Yes. The free KeyPitch Chrome extension adds loop controls right on YouTube and YouTube Music, so you can set an A–B loop around a single bar, a hand-crossing or a fast run and repeat it as many times as you need — slowed down and in any key. Looping the exact bars you're struggling with is the fastest way to nail a difficult passage on piano.

Yes. Install the free KeyPitch Chrome extension and it adds a pitch, key and speed panel right on YouTube and YouTube Music. While you practice you can transpose any video up or down — by exact semitones or in fine Hz steps — slow it down and loop a passage, with no download or conversion. It's perfect for playing along to a tutorial, a backing track or your favourite song in a key that suits your hands or your singer.

A great piano practice tool lets you slow songs down without dropping the pitch, change the key to fit your level or your singer, and loop the tricky bars. KeyPitch does all three: a free Chrome extension for practising live on YouTube and YouTube Music, and a browser-based Audio Studio for your own files — no software to install. You can preview everything for free and download your edited practice tracks to work on them offline.

Use the Pitch (Hz) slider to fine-tune a track, or send it to the Audio Studio to transpose by exact semitones. To accompany a singer, move the song up or down until it sits in their comfortable range; to match a recording tuned to 432 Hz, set the reference pitch to 432 Hz. The key changes while the tempo stays the same, so you can play the accompaniment without rewriting a single note.

Yes — that's exactly what KeyPitch is built for. Move the pitch or the semitones and the key changes while the tempo and length stay the same. It's ideal for transposing a piece into an easier key for your hands, dropping a song into a singer's range, or matching a backing track to another instrument, without it speeding up or slowing down.

Yes. KeyPitch uses time-stretching (SoundTouch) to change speed and pitch independently, so you can slow a blistering run or arpeggio right down and every note keeps its original pitch — no detuned, underwater sound. Learn the part slowly in tune, hands separately if you like, then bring the speed back up as your fingers catch on.

Drop a backing track or accompaniment into KeyPitch and you can put it in a comfortable key, slow it down to lock in your timing, and loop the section you're working on. When it sounds right, download it from the Audio Studio and practise along offline, anytime — at full speed or slowed down, in the original key or transposed to fit your hands.

Definitely. Beginners benefit most from slowing songs down and looping short sections, so you can learn one bar or one hand at a time instead of struggling at full speed. You can also move a piece into an easier key. As you improve, push the speed back toward 100% — it's a natural way to build up to the real tempo.

Yes. Advanced and expert pianists use KeyPitch to transcribe fast passages by ear, drill technical runs in a precise loop, transpose pieces for accompaniment or students, and match tracks to 432 Hz. Fine Hz control and exact-semitone transposition give you the precision serious practice needs.

Absolutely. Piano teachers use the Chrome extension to slow down and loop passages live during lessons on YouTube, and the Audio Studio to prepare practice tracks in the right key and tempo for each student. Export the track and send it home so your student can keep practising between lessons in exactly the version you worked on together.

KeyPitch accepts MP3, WAV, M4A and MP4 files up to 50 MB and 10 minutes — enough for most songs, accompaniment tracks, lesson videos and karaoke files. When you change the pitch or speed of an MP4 the picture stays intact and only the audio is processed, so you can keep a full video to play along to. The Audio Studio exports as MP3 or WAV.

Yes. Once you've set the pitch, key and speed, click Download and the track opens in the KeyPitch Audio Studio, where you can fine-tune and export it as MP3 or WAV. Keep your slowed-down, transposed practice versions on your phone or computer and rehearse anywhere — no internet needed.

Yes — uploading a file, changing its pitch, key and speed and previewing the result is completely free, and the Chrome extension for YouTube and YouTube Music is free too. You only pay when you want to download a finished practice track from the Audio Studio. You can pay per export, buy a discounted pack of exports, or take a subscription for unlimited downloads — handy if you prepare a lot of practice tracks.

Many pitch changers only handle uploaded files, tie speed to pitch, or watermark your exports. KeyPitch combines both worlds for piano players: a free Chrome extension to change pitch, key and speed and loop passages live on YouTube and YouTube Music, plus a browser Audio Studio for your own files with clean, downloadable exports. Pitch and speed stay independent, it supports audio and video, and an unlimited subscription means you can build a whole library of practice tracks.
