Learn how mood and danceability metrics help you understand your track’s emotional tone and rhythmic appeal.
Mood is categorized based on a calculated happiness (valence) score. The score combines energy levels with key detection:
Tracks in major keys are perceived as happier and receive a score boost, while minor key tracks reflect a more somber tone.
Danceability measures how suitable a track is for dancing, based on rhythm, tempo, and overall beat strength:
Tracks with high energy and strong rhythmic patterns are typically classified as highly danceable.

We extract fundamental audio features, including spectral patterns, harmonic content, and transient data, to provide a detailed and comprehensive analysis of your track. This deep low‑level analysis is essential for accurate key, BPM, and overall music profiling.
Our advanced harmonic analysis examines chord progressions, scales, and melodic structures to provide deep insights into musical compatibility and mixing potential. Enhance your DJ sets and music production with accurate harmonic and key compatibility metrics.
Different tools use different algorithms to calculate key and BPM. Our analyzer relies on cutting-edge audio analysis powered by the renowned Music Technology Group at UPF and other cutting edge AI and Machine Learning, which may differ from proprietary algorithms used by Spotify or Mixed In Key. Variations in audio files (e.g., remastered versions) can also affect results.
Our results are highly accurate, tested against industry-leading tools and large datasets. While no algorithm is 100% perfect, you can trust our analyzer to deliver results on par with commercial software like Mixed In Key and Serato DJ.
Your privacy is important to us. Audio files are all processed on the fly and not stored on our servers, ensuring complete data privacy.
We support a wide range of audio formats, including MP3, WAV, FLAC, and AAC. If your file is not supported, consider converting it to one of these formats using free tools like Audacity.
Absolutely! DJs and live performers often rely on accurate key and BPM detection for harmonic mixing and tempo matching. Our analyzer provides quick, reliable results, making it an excellent tool for preparation or live adjustments.
There are several free tools available for detecting the key and BPM of a song. Examples include Mixxx, an open-source DJ software with built-in key and BPM detection, and our free online analyzer. These tools are perfect for DJs, producers, and anyone looking to improve their mixes without breaking the bank.
Key and BPM detection tools analyze audio files using algorithms that detect tempo and harmonic content. They calculate beats per minute (BPM) by identifying rhythmic patterns and determine the musical key by analyzing harmonic frequencies. Advanced tools often use machine learning for more accurate results, making them invaluable for music production and DJing.
Yes, many key and BPM detection tools are designed for real-time analysis, making them ideal for live performances. DJ software like Traktor and Serato DJ Pro provide accurate BPM and key detection during live sets, enabling seamless transitions and harmonic mixing on the fly.
Key detection works by analyzing the harmonic frequencies within an audio file to determine its tonal center and scale. Algorithms identify patterns in the audio's pitch content, comparing them to predefined key profiles (such as major and minor scales). Tools like ours use advanced mathematical models and machine learning to improve accuracy, ensuring reliable results for musicians and DJs.
The Camelot system is a visual way of organizing musical keys to make harmonic mixing easier. It helps DJs and producers match tracks with compatible keys for smoother transitions and better-sounding mixes.
Energy in music is a measure of intensity and activity, influenced by elements like tempo, dynamics, and instrumentation. High-energy tracks are great for lively moments, while low-energy tracks create relaxed atmospheres.
Danceability refers to how suitable a track is for dancing, based on factors like tempo, rhythm stability, and beat strength. Tracks with high danceability scores are perfect for parties and energetic playlists.
Happiness in music is measured using audio features like key, tempo, and chord progressions, which influence the emotional tone of a song. Upbeat tempos and major keys often result in higher happiness scores.
Using the Camelot system, you can mix tracks with keys that are harmonically compatible, such as moving clockwise or counterclockwise on the Camelot wheel. This ensures seamless transitions and enhances the flow of your set.
Energy levels help determine the mood and purpose of a playlist. High-energy songs keep listeners engaged during workouts or parties, while low-energy songs are ideal for relaxation and focus.
Understanding danceability helps you create playlists tailored to specific events, such as dance parties or casual gatherings. It ensures you choose tracks that resonate with the desired atmosphere.
Absolutely! Songs with high happiness levels can uplift listeners, making them feel more positive and energized. This is why many upbeat tracks are used in motivational playlists and feel-good moments.
