Plain-English explainers for BPM, Camelot, harmonic mixing, MIDI, LUFS and the rest. Each article links to a free tool you can try.
BPM stands for beats per minute — it's the tempo of a song. A 120 BPM track has 120 beats every 60 seconds. BPM is one of the first things producers, DJs and sync editors check on any track.

4 minRead →Harmonic Mixing · DJThe Camelot Wheel is a circular reference for DJs that maps every musical key to a number 1-12 plus a letter — A for minor keys, B for major. Adjacent codes are harmonically compatible, so DJs can mix in key without studying music theory.
5 minRead →DJ TechniqueHarmonic mixing means blending two tracks whose musical keys are compatible, so the transition sounds smooth instead of clashing. DJs use the Camelot Wheel to find compatible tracks at a glance — and modern software detects key automatically.
4 minRead →ProductionStems are isolated layers of a song — typically vocals, drums, bass and music (everything else) — exported as separate audio files. Producers use them to remix, sample, create karaoke versions or simply study how a track was put together.
4 minRead →MasteringLUFS (Loudness Units relative to Full Scale) is the modern standard for measuring perceived loudness. Streaming platforms normalise tracks to a target LUFS — Spotify −14, Apple Music −16 — so listeners hear consistent volume without manually adjusting each song.
5 minRead →MasteringTrue-peak measures the actual analog peak of your audio, including inter-sample peaks that don't show up on a sample-peak meter. Critical for streaming masters because lossy encoders (MP3, AAC) can push the audio over 0 dBFS and cause distortion.
3 minRead →Production · MIDIMIDI (Musical Instrument Digital Interface) is a protocol for music data. A MIDI file stores notes — what pitch, when they start, how long they last, how hard they're played — but no audio. Any synth or sampler can play those notes back with its own sound.
5 minRead →ProductionSampling means taking a snippet of an existing recording — a drum break, a vocal phrase, a single chord — and reusing it as a building block in a new song. It's the foundation of hip-hop and electronic music, and it's everywhere in pop.
4 minRead →Music TheoryA major key sounds bright, hopeful or triumphant. A minor key sounds sad, mysterious or tense. The difference is one note — the third of the scale is a half-step lower in minor — but it changes everything emotionally.
4 minRead →Music AnalysisKey detection identifies the musical key of any song from its audio. AI-powered detectors return the tonic (e.g. C), the mode (major or minor), and the matching Camelot code in seconds. Producers, DJs and singers all use it.
4 minRead →SongwritingA chord progression is the sequence of chords in a song — the harmonic spine that everything else hangs off. Most popular music recycles the same handful of progressions because they're emotionally reliable. Learning a few unlocks endless songwriting.
5 minRead →Music TheoryModes are variations of the major scale that start on different notes, giving each its own colour. There are seven — Ionian (the major scale), Dorian, Phrygian, Lydian, Mixolydian, Aeolian (the minor scale) and Locrian. Producers use them to find a sound between "happy" and "sad".
4 minRead →Production · MasteringMixing balances the individual tracks within one song — it's about getting the vocal, drums, bass and synths to sit right together. Mastering is the final polish on the finished mix — getting the song loud enough, consistent across the album, and ready for streaming.
5 minRead →Camelot · DJCamelot 8A is the DJ-friendly notation for the musical key A minor. Tracks at 8A mix harmonically with 7A (D minor), 9A (E minor) and 8B (C major). It's one of the most popular keys in modern dance music.
