G is then 5 steps away from the root (C) making it the 5th. The 1st note (in this case C) is called the root, after that you count steps away, starting with C - making the 3rd E. Since triad chords are built by using every other note from the one you begin on - a C Major chord would be CEG. For example in the key of C the scale would be CDEFGABC. The scale numbers would look like this I ii iii IV V (the 5th should have lines above to show its Major) vi vii(o) I. The remaining chords are minor with the exception of the 7th which is diminished. The I, IV, and V are the only major chords in a traditional major scale. The formula to make a Major scale is the same for every single Major key. In western music chords are traditionally built by using every other note beginning on each scale degree - giving you a choice of 7 diatonic chords in a Major scale. Upper case represents a Major chord, lower case are minor chords, and lower case with a little circle in the upper righthand corner of the Roman numeral is diminished. The scale degrees are numbered with Roman numerals so that you can use upper and lower case letters. Each scale degree represents a potential chord. Each note in the scale is called a scale degree. There are four different types: major, minor, diminished and augmented.A Major scale has 7 different notes and then ends back on 1, making a total of 8 notes. Triad means three notes. You may not have used the expression triad or triad chords but these are the basic building blocks of chord theory. Slash chords or split chords are where the lowest note in the chord is not the root note. A half-diminished chord is a diminished triad with a major third on top. For a full diminished add another minor 3rd interval on top. diminished chordsĪ diminished triad uses two minor 3rd intervals stacked on top of each other. These chords have a feeling of "suspension" where the sus4 or sus2 wants to resolve to the 3rd of the chord. With a suspended chord, where the third would normally be in a major or minor triad, this is replaced by a perfect fourth or a major second. A minor sixth chord contains a minor triad with minor sixth interval on top. If not specified the chord will have a major triad with a major sixth interval above. sixth chordsĪ sixth chord contains a triad with a sixth interval on top. A major seventh chord contains a triad with the third being a major third and with a major seventh interval. A minor seventh chord contains a minor triad with minor seventh interval. If not specified the seventh will be the 'dominant' seventh, which means a major triad with a minor seventh interval above. seventh chordsĪ seventh chord contains a triad with a seventh interval on top. minor chordsĪ mnior chord contains a root, minor third and a perfect fifth and is considered to sound quite melancholic or sad :(. There is a link to triad chords at the bottom, have a look at this as it helps explain the building blocks of chord and chord theory.Ĭhords can be separated into these groups: major chordsĪ major chord contains a root, major third and a perfect fifth and is considered to sound quite upbeat or happy :). The descriptions of the chord types listed below refer to the music intervals, triads and other stuff which is covered in the music theory section. The 3rd is missing from this chord and therefore you cannot tell whether it is a major or minor chord. This is not officially a chord but makes a lot of sense to guitar players who use this kind of "chord" all the time, especially if you play hard rock, grunge, metal etc. There is also a modern convention of showing a power chord or fifth interval (which has only 2 notes) as a "5" chord. A guitar chord or chord on any instrument is a group of three or more notes played back in quick succession or together.
