Basic music theory terms
-
Musical note - a pitch and duration of sound.
-
Accidental - a symobol, which changes the pitch of a note. Most common accidentals are: sharp, flat and natural.
-
Pitch - property of sounds, which allows their ordering on a frequency - related scale.
-
Scale - a set of musial notes ordered by fundamental frequency (or pitch). A scales spans a single octave.
-
Based on their intervals, scales are divided into categories like minor and major.
-
Key signature - a set of sharp, flat and natural symbols, which desigates notes, which are to be played higher or lower than corresponding natural notes.
-
Fretboard - part of the guitar between the nut and the bridge.
-
Interval - a recoginzable distance between two successive notes in the scale. Five - note scale has 10, while in seven - note scale one can find 21 intervals.
-
Pentatonic scale - a scale with 5 notes per octave.
-
Heptatonic scale - a scale with 7 notes per octave.
-
Mode - a scale together with a set of characteristic melodic behaviours.
-
Relative scale - a minor and major key, which have the same signature and which differ by no more than one accidental.
-
Modulation - the act of changing from one key to another.
-
Chord - any charmonic set of pitches consisting of two of more notes (also called pitches) played simultaneously.
-
Chord progression - a succession of two or more musical chords. Alternation between two chords may be thought of as the most basic chord progression.
-
Scale degree - the position of a particular note on a scale relative to the tonic - the first and the main note of the scale.
-
Backcycling
Backcycling is a process of extending a chord progression based on creating one or more extra dominant-to-tonic movements, or if taken further - re-creating the whole original chord progression.
