1️⃣ Enter the original BPM and the target BPM of your song or
track.
2️⃣ The tool automatically calculates the pitch shift in semitones needed to match
tempo changes.
3️⃣ Use this to adjust your track’s key accurately in your DAW or mixing software.
4️⃣ Ideal for DJs, producers, and musicians who want to blend or remix tracks seamlessly.
The BPM Pitch Calculator is a powerful tool that helps music producers, DJs, and podcasters understand how tempo (BPM) and pitch relate to each other. When you speed up or slow down a song, its pitch changes — and this calculator instantly tells you by how many semitones that shift occurs.
A BPM Pitch Calculator converts tempo changes into pitch differences. If you increase a track’s BPM, the pitch rises; slow it down, and the pitch drops. This helps in remixing, syncing multiple tracks, or keeping vocals natural while adjusting playback speed.
Pitch and tempo are mathematically connected. For every 6% change in tempo, pitch shifts by roughly one semitone. For instance, going from 120 BPM to 127 BPM increases pitch by +1 semitone. This small change can make or break harmonic balance when DJing or mastering music.
| Original BPM | Target BPM | Pitch Change |
|---|---|---|
| 100 | 110 | +1.65 semitones |
| 120 | 130 | +1.35 semitones |
| 90 | 80 | -2.12 semitones |
Mixing tracks with different tempos can distort the sound or ruin key alignment. A BPM Pitch Calculator ensures harmonic matching — so when you change BPM, your tracks stay in tune. It’s an essential utility for DJs and music producers who mix across genres or transition between tempos live.
The mathematical formula for calculating pitch difference between two tempos is:
Pitch Shift (in semitones) = 12 × log₂(Target BPM / Original BPM)
This means doubling your BPM raises the pitch by one octave (+12 semitones). The calculator uses this formula instantly — saving you from manual math and ensuring accuracy every time.
Many creators ask: Is 70 BPM too slow? Not necessarily — 70 BPM works great for ballads or chill-hop. Is 120 BPM fast? It’s actually one of the most common tempos for dance music. Understanding these nuances helps you make better mixing decisions.
The BPM Pitch Calculator from Diamond Audio City helps you understand tempo-to-pitch relationships instantly — no complex math or software required. Whether you're syncing two tracks or mastering your mix, this calculator keeps your sound precise and musical.

12 × log₂(New BPM ÷ Original BPM).
The result gives the semitone shift — positive for higher pitch, negative for
lower.
