Harmonic Mixing
Harmonic mixing or key mixing (also referred to as mixing in key) is a DJ technique of matching the musical key of tracks in a DJ mix to avoid dissonance and create harmonious mixes or mashups. Tracks may be matched if they are in the same key, if their keys are relative, or if their keys are in a subdominant or dominant relationship with one another. The Camelot wheel is based on the circle of fifths and can be used for harmonic mixing. Modern DJ software (such as VirtualDJ, Serato, and Rekordbox) can use algorithms to determine a track's key. Mixed In Key is specialized software designed for more accurate key detection and is compatible with some other DJ software. Other methods to determine key include the use of AI or looking up tracks in an online database.https://www.musicradar.com/news/getsongkeycom-gives-you-essential-music-theory-information-about-more-than-6-million-songs Some DJ software and hardware can also pitch shift a track to change its key to one tha ...

Disc Jockey
A disc jockey, more commonly abbreviated as DJ, is a person who plays recorded music for an audience. Types of DJs include Radio personality, radio DJs (who host programs on music radio stations), club DJs (who work at nightclubs or music festivals), mobile DJs (who are hired to work at public and private events such as weddings, parties, or festivals), and turntablism, turntablists (who use record players, usually turntables, to manipulate sounds on phonograph records). Originally, the "disc" in "disc jockey" referred to shellac and later vinyl records, but nowadays DJ is used as an all-encompassing term to also describe persons who DJ mix, mix music from other recording media such as compact cassette, cassettes, Compact disc, CDs or digital audio files on a CDJ, controller, or even a laptop. DJs may adopt the title "DJ" in front of their real names, adopted pseudonyms, or stage names. DJs commonly use audio equipment that can play at least two sources of recorded music simul ...

Circle Of Fifths
In music theory, the circle of fifths (sometimes also cycle of fifths) is a way of organizing pitches as a sequence of perfect fifths. Starting on a C, and using the standard system of tuning for Western music (12-tone equal temperament), the sequence is: C, G, D, A, E, B, F/G, C/D, G/A, D/E, A/B, F, and C. This order places the most closely related key signatures adjacent to one another. Twelve-tone equal temperament tuning divides each octave into twelve equivalent semitones, and the circle of fifths leads to a C seven octaves above the starting point. If the fifths are tuned with an exact frequency ratio of 3:2 (the system of tuning known as just intonation), this is not the case (the circle does not "close"). Definition The circle of fifths organizes pitches in a sequence of perfect fifths, generally shown as a circle with the pitches (and their corresponding keys) in clockwise order. It can be viewed in a counterclockwise direction as a circle of fourths. Harmonic progres ...

Segue
A segue ( , ; ) is a transition from one topic or section to the next. In music In music, ''segue'' is a direction to the performer. It means ''continue (the next section) without a pause''. The term ''attacca'' is used synonymously. For written music, it implies a transition from one section to the next without any break. In improvisation, it is often used for transitions created as a part of the performance, leading from one section to another. In recorded music, a segue sometimes means a seamless change between one song and another, sometimes achieved through beatmatching, especially on dance and disco recordings. However, as noted by composer John Williams in the liner notes for his Star Wars soundtrack album, a series of musical ideas can be juxtaposed with no transitions whatsoever. Arrangements that involve or create the effect of a classical musical suite, may be used in many pieces or progressive rock recordings, but by definition, a segue does not involve a brid ...

Beatmatching
Beatmatching or pitch cue is a DJ technique of pitch shifting or time stretching an upcoming track to match its tempo to that of the currently playing track, and to adjust them such that the beats (and, usually, the bars) are synchronized—e.g. the kicks and snares in two house records hit at the same time when both records are played simultaneously. Beatmatching is a component of beatmixing which employs beatmatching combined with equalization, attention to phrasing and track selection in an attempt to make a single mix that flows together and has a good structure. Beatmatching is a core technique for DJing electronic dance music, and it is standard practice in clubs to keep a constant beat throughout the night, even if DJs change in the middle. Technique The beatmatching technique consists of the following steps: # While a record is playing, start a second record playing, but only monitored through headphones, not being fed to the main PA system. Use gain (or ' ...

Pitch Shifting
Pitch shifting is a sound recording technique in which the original pitch of a sound is raised or lowered. Effects units that raise or lower pitch by a pre-designated musical interval ( transposition) are known as pitch shifters. Pitch and time shifting The simplest methods are used to increase pitch and reduce durations or, conversely, reduce pitch and increase duration. This can be done by replaying a sound waveform at a different speed than it was recorded. It could be accomplished on an early reel-to-reel tape recorder by changing the diameter of the capstan or using a different motor. As for vinyl records, placing a finger on the turntable to give friction will slow it, while giving it a "spin" can advance it. As technologies improved, motor speed and pitch control could be achieved electronically by servo drive system circuits. Pitch shifter and harmonizer A pitch shifter is a sound effects unit that raises or lowers the pitch of an audio signal by a preset interval ...

Serato
Serato (stylized in all lowercase; ) is a music software company founded in 1998 in Auckland, New Zealand by Steve West and AJ Bertenshaw. History West and Bertenshaw met in computer science class at the University of Auckland. When West created an algorithm that could change the tempo of a recorded track without changing its pitch, Bertenshaw realized the opportunity to build upon the idea. The first published product, "Pitch 'n Time", which built off the original audio manipulation concept, was pitched to various companies like Pioneer and Sony but failed to gain traction with the music side of the industry. However, the idea was received more positively in Hollywood, where it quickly became useful editing tool for moviemakers. Software Serato DJ Serato DJ is digital music mixing software for DJing. Serato DJ supports DJ mixing with digital music files and streaming music and is compatible with digital DJ controllers or digital vinyl. Serato DJ has visual components incl ...

Mixed In Key
Mixed In Key (also known as MIK) is Windows and Macintosh software that simplifies a DJ technique called harmonic mixing. Mixed In Key analyses MP3 and WAV files and determines the musical key of every file. Knowing the key, DJs can use music theory (such as the Circle of Fifths) to play songs in a harmonically-pleasing order. The software helps to solve Mixed In Key's software was developed to provide a Windows interface for the toner key detection algorithm created by zplane.development. The original tONaRT algorithm created by zplane.development had a simple Windows-based demo which could not process multiple audio files at once. Yakov Vorobyev created a simple C# .NET Windows application that could batch-process multiple files. he first version was released on March 25, 2006. Soon after, work on Mac OS X began, and on June 4, 2006, the first version of Mac OS X was released. Since May 2007, Mixed In Key, LLC has improved the key detection algorithm by combining tONaRT w ...

Key (music)
In music theory, the key of a piece is the group of pitches, or scale, that forms the basis of a musical composition in Western classical music, jazz music, art music, and pop music. A particular key features a '' tonic (main) note'' and its corresponding '' chords'', also called a ''tonic'' or ''tonic chord'', which provides a subjective sense of arrival and rest. The tonic also has a unique relationship to the other pitches of the same key, their corresponding chords, and pitches and chords outside the key. Notes and chords other than the tonic in a piece create varying degrees of tension, resolved when the tonic note or chord returns. The key may be in the major mode, minor mode, or one of several other modes. Musicians assume major when this is not specified; for example, "this piece is in C" implies that the key of the piece is C major. Popular songs and classical music from the common practice period are usually in a single key; longer pieces in the classical repe ...

Subdominant
In music, the subdominant is the fourth tonal degree () of the diatonic scale. It is so called because it is the same distance ''below'' the tonic as the dominant is ''above'' the tonicin other words, the tonic is the dominant of the subdominant. It also happens to be the note one step below the dominant. In the movable do solfège system, the subdominant note is sung as ''fa''. The triad built on the subdominant note is called the subdominant chord. In Roman numeral analysis In music theory, Roman numeral analysis is a type of Harmony, harmonic analysis in which chord (music), chords are represented by Roman numerals, which encode the chord's Degree (music), degree and Function_(music), harmonic function within a given ..., the subdominant chord is typically symbolized by the Roman numeral "IV" in a major key, indicating that the chord is a major triad. In a minor key, it is symbolized by "iv", indicating that the chord is a minor triad. These chords may also appear ...
