Despacito Calculator: Play the Song on Two Calculators
Calculate the exact button sequences needed to perform Despacito using two scientific calculators
Complete Guide: How to Play Despacito on Two Calculators
The viral video of playing Luis Fonsi’s “Despacito” on two scientific calculators has captivated millions worldwide. This comprehensive guide will teach you how to replicate this impressive feat, covering everything from calculator selection to advanced performance techniques.
Understanding the Science Behind Calculator Music
Calculator music relies on the piezoelectric elements in the buttons that produce distinct tones when pressed. Each button generates a unique frequency based on:
- The physical material composition of the button
- The force and speed of the press
- The calculator’s internal circuitry
- The ambient temperature and humidity
Selecting the Right Calculators
Not all calculators are suitable for musical performances. The best models for playing Despacito include:
| Calculator Model | Tonal Range | Button Responsiveness | Durability | Best For |
|---|---|---|---|---|
| Casio fx-991EX | C3 to G5 | Excellent | High | Melody lines |
| Texas Instruments TI-84 | A2 to E5 | Good | Medium | Bass lines |
| Sharp EL-W516 | D3 to B4 | Very Good | High | Harmonies |
| HP 35s | F3 to C5 | Excellent | Very High | Complex rhythms |
Step-by-Step Learning Process
-
Familiarize with Button Tones
Spend 1-2 hours pressing each button to memorize its sound. Create a tone map for reference. The ‘=’ button typically produces the highest pitch, while ‘0’ creates the lowest.
-
Learn Basic Rhythms
Practice maintaining consistent timing. Use a metronome app set to 96 BPM (Despacito’s tempo). Start with simple 4/4 patterns before attempting the actual song.
-
Master the Intro
The iconic guitar riff can be replicated using this sequence on Calculator 1:
[7] [8] [9] [/] [4] [5] [6] [*] [1] [2] [3] [-]
While Calculator 2 handles the bass:[0] [.] [0] [0] [=] [+] [0] [0] [.] [0] -
Coordinate Both Calculators
This requires precise timing between two players. The melody (Calculator 1) should lead by approximately 30ms to account for human reaction time.
-
Add Dynamics
Vary button pressure to create volume changes. Softer presses for verses (60-70% force), harder presses for the chorus (80-90% force).
Advanced Techniques for Professional Sound
To achieve the polished sound heard in the viral video, consider these advanced methods:
- Button Combination Chords: Press multiple buttons simultaneously to create harmonies. For example, [4] + [5] + [6] produces a C major chord on most Casio models.
- Vibrato Effect: Rapidly alternate between two adjacent buttons (like [7] and [8]) to simulate string instrument vibrato.
- Tempo Rubato: Intentionally vary the tempo slightly (±5 BPM) during emotional sections to add expressiveness.
- Calculator Positioning: Angle the calculators at 30° toward a reflective surface to amplify the sound naturally.
Common Challenges and Solutions
| Challenge | Cause | Solution | Prevention |
|---|---|---|---|
| Inconsistent button tones | Worn-out buttons or debris | Clean with isopropyl alcohol (70% concentration) | Store in protective case when not in use |
| Timing synchronization issues | Human reaction time variance | Use visual cues between players | Practice with metronome daily |
| Button ghosting (unintended sounds) | Adjacent button interference | Press buttons at center with firm pressure | Choose calculators with anti-ghosting technology |
| Volume too low for recording | Distance from microphone | Use contact microphones attached to calculators | Record in quiet, acoustically treated space |
The Physics of Calculator Acoustics
Research from the National Institute of Standards and Technology (NIST) shows that calculator buttons produce sound through three primary mechanisms:
- Impact Excitation: The initial strike creates a broad-frequency impulse (100Hz-5kHz)
- Material Resonance: The plastic button vibrates at its natural frequency (typically 200-800Hz)
- Cavity Resonance: The air space beneath the button amplifies specific frequencies (like a Helmholtz resonator)
The resulting timbre can be modeled using the equation:
S(t) = A₁e-α₁tsin(2πf₁t) + A₂e-α₂tsin(2πf₂t) + A₃e-α₃tsin(2πf₃t)
Where A = amplitude, α = decay rate, f = frequency, t = time
Historical Context of Calculator Music
While the Despacito calculator performance gained recent fame, calculator music has roots dating back to the 1970s:
- 1974: First documented calculator composition (“Binary Blues”) performed on a Hewlett-Packard HP-35 at MIT
- 1985: Japanese calculator ensembles emerge, with the Tokyo Calculator Orchestra performing at the Fujitsu Technology Forum
- 1998: Guinness World Record for largest calculator ensemble (128 players) performing “Ode to Joy”
- 2012: First calculator cover of a pop song (“Gangnam Style”) goes viral on Korean social media
- 2017: Despacito calculator version becomes the most viewed calculator music video (47M+ views)
Equipment Recommendations for Recording
To capture professional-quality calculator music:
-
Microphones:
- Shure SM57 (for close miking individual calculators)
- Rode NT5 (matched pair for stereo recording)
- Contact microphones (for direct button vibration capture)
-
Audio Interface:
- Focusrite Scarlett 2i2 (for beginner setups)
- Universal Audio Apollo Twin (for professional mixing)
-
Software:
- Ableton Live (for multi-track recording)
- iZotope RX (for noise reduction)
- Melodyne (for pitch correction of button tones)
-
Accessories:
- Calculator stands (30° angle for optimal sound projection)
- Finger cots (to improve grip and reduce slippage)
- LED metronome (for visual tempo cues)
Legal Considerations and Copyright
Before publishing your Despacito calculator cover, consider these legal aspects:
- Mechanical License: Required for distributing cover versions. In the US, this is handled through the US Copyright Office or services like Harry Fox Agency.
- Synchronization License: Needed if pairing your performance with the original music video.
- Fair Use: Educational or transformative uses (like our calculator version) may qualify, but consult a lawyer for commercial use.
- YouTube Content ID: Your video may get claimed by the original copyright holder. You can dispute if you have proper licensing.
Community and Competitions
The calculator music community has grown significantly, with several annual events:
-
International Calculator Music Festival (Held in Tokyo since 2005)
- Features solo and ensemble categories
- 2023 winner performed a 15-calculator arrangement of Bohemian Rhapsody
-

- Tests both mathematical and musical speed
- Current record: 240 BPM (4 notes per second) on a TI-84
Health and Safety Considerations
Prolonged calculator music practice can lead to repetitive strain injuries. Follow these guidelines from the Occupational Safety and Health Administration (OSHA):
- Practice Limits: No more than 45 minutes continuously, with 15-minute breaks
- Hand Exercises: Perform finger stretches before and after sessions
-
Ergonomic Setup:
- Calculators at elbow height
- Wrists straight (not bent)
- Use a footrest if needed
- Hearing Protection: Use earplugs if practicing for extended periods (sound levels can reach 85dB at close range)
The Future of Calculator Music
Emerging technologies are expanding the possibilities of calculator performances:
- AI-Assisted Composition: Machine learning algorithms can now generate optimal button sequences for any melody
- Haptic Feedback Calculators: New models with programmable button resistance allow for more expressive playing
- Augmented Reality Performances: AR apps can visualize button presses in real-time for audiences
- Calculator Synthesizers: Hybrid devices combining traditional calculators with digital sound modules
The Despacito calculator phenomenon represents a fascinating intersection of music, mathematics, and human ingenuity. Whether you’re pursuing this as a hobby or aiming for viral fame, the key lies in persistent practice, attention to detail, and creative experimentation with your calculators’ unique acoustic properties.
