Basic triad chords are using the diatonic interval 1,3,5. Each chord in the scale has a different starting root position.
This page shows you the notes of chords within a scale. The chords are represented by roman numerals and are determined by key (in this case, the key of G). This can be used lookup how to play arpeggios, or how to create chords on different positions. If you are looking for more chords, check the chord overview page. Once you understand the basics, try experimenting with key changes and chord variations on your own.You can easily change the key by clicking the the note-switch in the title. Also, try to add sevenths by choosing "7th chord".
The basic chords in G natural major are: G, Am, Bm, C, D, Em and F♯dim
Look at the fretboard and find a position where the notes G, B and D are all on different strings and close to each other and play that. Next exercise is to find the same chord but on different positions on the neck.
If you keep all the notes of the major scale the same but change the tonal centre, you create a new scale or mode. Basically, a mode is a scale created by setting a new root note from the given scale. Modes are so to say a different way of thinking about scales and keys. Using modes allows us to assign an individual mode/scale to every single chord in a progression.
The current table shows the triad chords within the major scale and also the mode that can be used.
|Roman||Chord name||Chord notes||Related mode|
|I||G||G, B, D||G Ionian scale mode|
|ii||Am||A, C, E||A Dorian scale mode|
|iii||Bm||B, D, F♯||B Phrygian scale mode|
|IV||C||C, E, G||C Lydian scale mode|
|V||D||D, F♯, A||D Mixolydian scale mode|
|vi||Em||E, G, B||E Aeolian scale mode|
|vii°||F♯dim||F♯, A, C||F♯ Locrian scale mode|

Difference between chords or arpeggios
Chords and arpeggios are similar as they share the same notes. Chords are played together and strummed. Chord may repeat some of the notes from the chord. For example if you play the good old Em chord, you can play all the strings, so you play 6 notes. But actually you only play the notes E, G and B so some notes are played multiple times but in different octaves. Arpeggios are created from chords notes but played one note at a time. While playing arpeggios, its likely you play multiple notes on the same string, so you can’t hold your fingers in one shape.
The roman numbers in music
Because all the note-to-note relationships in music are permanent, you can use symbols as a time-saving shorthand to understand how chords work in your music.
In the roman numeral system for chords, I (or i) means one, and V (or v) means five.
Harmonic analysis uses roman numerals to indicate chords in the music.
The numeral indicates the scale step (scale degree) of the root of the chord.
The format of the roman numeral indicates the chord quality, as follows:
- For major or augmented chords, an uppercase Roman numeral is used. Example: I, II, III, etc.
- For minor or diminished chords, a lowercase Roman numeral is used. Example: i, ii, iii, etc.
- For diminished chords, a ° (degree) sign is added. Example: vi°, vii°, etc.
- For augmented chords, a + (plus) sign is added. Example: I+, II+, III+, etc.
- For half-diminished chords, a Ø sign is added. Example: viiØ7, etc.
- For extended chords, numbers are added. Example: ii7, V9, V13, etc.
- For altered tones/chords, either ♯ or ♭ is added. Example: ♯iv, ii♯7, , ♭III
Chord progressions are series of two or more chords used in a piece of music.
Don’t limit yourself
The (diatonic) major scale in key of G consist of 7 notes; G, A, B, C, D, E and F♯. Of course there is no reason to restrict yourselves to only those notes. Scales can have more or fewer notes; all the way up to the chromatic scale (12 notes). In some styles it’s very common to add extra notes every now and then, you can get away with many things in music. You can also limit yourself to be more safe, for example the pentatonic scales only have 5 notes.Some say you cannot play wrong notes. Some might sound more dissonant than others, but you are always one semi-tone away from being in scale. This site gives you a reference of how the theory works, but it’s exciting to find out that music is always about breaking the rules.
