Line 1:
Line 1: − + − ==Primary Chords==+ − The primary chords of a scale are triads built upon the 1st, 4th and 5th scale degree. For example, if we were in C major, the primary chords are: C major , F major and G major. The tonality of the primary chords relies on the piece's key signature (being major or minor). These chords are widely used throughout contemporary and country music. They are called primary chords as the notes in each chord can be unjumbled to create the major scale they represent.+ − ==Secondary Chords==+ − Secondary chords represent the rest of the scale degrees, being: 2nd, 3rd, 6th and 7th. Secondary chords carry the opposite tonality of the piece's key signature. For example, C major's secondary chords are: D minor, E minor and A minor. The only exception to this rule is that the 7th scale degree (B) is a diminished triad.+ − ==Relative keys==+ − In music, certain keys can be related to each other since they have identical key signatures (equal number of sharps or flats). For example, D major and B minor are relative major/minor keys since they both have two sharps in their key signature.+ − − [[Category:Music]]
Complete restart. I will add to this later.
'''Music theory''' is the subject of [[composition]], scales, intervals and chords.
'''Music theory''' is the field of study which analyses the various features of music in order to understand how music works. The components analysed include:
'''Pitch''': How high or low the notes sound, which is a result of the soundwave's frequency. The continuous spectrum of possible frequencies is divided into discrete, named units called notes. Every doubling in frequency (between, for example 100Hz and 200Hz, or between 200Hz and 400Hz), is known as an octave. Any two notes whose frequencies are in a 2:1 ratio share the same name. So, for example, the A above middle C has a frequency of 440 Hz. The notes with double or quadruple that frequency (880, 1760, ...) and the notes with a half or quater that frequency (220, 110, ...) are also named A.
In Western music, each octave is divided into twelve notes.
'''Melody''': A group of notes played in sequence. Melody is usually subdivided into phrases, which collectively form a structure.
'''Rhythm''': How the notes are organised temporally, and their relative durations. Most music contains a repeating pattern of stressed and unstressed beats. On the page, in what is known as Standard Notation, the start of each new unit of this pattern is marked by a vertical line known as a barline. Each such unit is referred to as a measure or a bar. The first beat of every bar is normally the most heavily emphasised, although the total number of beats is not always the same. A march typically has four beats per bar, while a waltz typically has three. The number of beats per bar is designated by a time signature.
'''Harmony''': Harmony is the study of notes which occur together or which are perceived as being together. This usually means notes which are played simultaneously, as in a chord, but can also apply to notes within a melody which outline a chord. The harmony that results from the combination of any two or more notes depends on the interval present between those notes. A system of Roman numerals is the most common means used to analyse harmony.
'''Form''': Form refers to the structural aspects of a piece of music. Basic examples of form include binary form (A - B), in which one section is followed by a contrasting section, or ternary form (A - B - A), in which the first section returns, usually in slightly altered form, to give a sense of formal closure.
