DJ Music Theory for DJs 1 — Questions and Answers
Question 1: What is 'harmonic mixing' in DJing?
- Mixing tracks with matched BPM only
- Mixing tracks whose musical keys are harmonically compatible to avoid clashing melodies (Correct answer)
- Applying harmonic distortion effects
- Using the mixer's harmonic EQ
Correct answer: Mixing tracks whose musical keys are harmonically compatible to avoid clashing melodies
Harmonic mixing involves selecting tracks with compatible keys so that melodies and basslines blend musically rather than clashing when mixed together.
Question 2: What is the Camelot Wheel used for by DJs?
- Calculating BPM differences
- Identifying harmonically compatible keys for smooth melodic transitions (Correct answer)
- Mapping out a DJ set timeline
- Organizing tracks by genre
Correct answer: Identifying harmonically compatible keys for smooth melodic transitions
The Camelot Wheel assigns numbers and letters to musical keys, allowing DJs to quickly identify which keys are harmonically compatible without music theory knowledge.
Question 3: In music theory, what is the difference between a major and minor key?
- Major keys are faster, minor keys are slower
- Major keys have a brighter, happier sound while minor keys have a darker, sadder feel (Correct answer)
- Major uses sharps, minor uses flats
- Major has 8 notes, minor has 7
Correct answer: Major keys have a brighter, happier sound while minor keys have a darker, sadder feel
Major keys use a scale pattern that sounds bright and happy, while minor keys use a different pattern that creates a darker, more melancholic emotional quality.
Question 4: What does the 'key' of a track refer to in music?
- The track's BPM range
- The root note and scale that defines the tonal center of the music (Correct answer)
- The track's loudness level
- The tempo signature
Correct answer: The root note and scale that defines the tonal center of the music
The key of a track refers to the root note and scale (major or minor) that establishes the tonal center around which all melodies and harmonies are built.
Question 5: What does it mean to mix 'in key' or 'key lock'?
- Using pitch correction to keep a track's key constant when changing its tempo (Correct answer)
- Locking the pitch fader at zero
- Mixing only tracks in the same BPM
- Preventing the crossfader from moving
Correct answer: Using pitch correction to keep a track's key constant when changing its tempo
Key lock (or master tempo) uses digital processing to keep a track's musical key constant even when its tempo is changed with the pitch fader.
Question 6: What are the 'circle of fifths' adjacent keys that harmonically compatible tracks often share?
- Keys 12 semitones apart
- Keys whose root notes are a perfect fifth apart, sharing most of the same notes (Correct answer)
- Keys with the same BPM
- Keys using the same time signature
Correct answer: Keys whose root notes are a perfect fifth apart, sharing most of the same notes
Keys adjacent on the circle of fifths (a perfect fifth apart) share most of their notes, making them naturally compatible for harmonic mixing.
