Comments

Open chord referring to the way a chord is constructed, not to a specific chord. An open chord can be a C or it can be a C7 or it can be a Cadd9. You can often play a certain chord as both a barre or as an open chord, the difference is the sound (and the shape of course).


The open chords suits very well on an acoustic guitar or electric guitar with clean sound from the amplifier. The tones rings out well and it has a pleasant crispy sound.


The drawback with open chord is that some chord has quite difficult fingerings. As you can see above you can choose from notes: C - D - E - F - G - A - B. The C# (or Db), D#, F#, G# and A# are missing. This is by the reason that these chords in many times have no natural fingerings in the standard tuning and therefore are often played as barre chords or with a capo.

Chord note structure

Here's information about which notes each chord consists of. Note that you sometimes are strumming more strings than the numbers of the notes of the chord you are playing, this is because some notes are duplicated, but in different octaves.


C:
C – E – G
Cm: C – Eb – G
Cmaj7: C – E – G – B
Cm7: C – Eb – G – Bb
C7: C – E – G – Bb
C6: C – E – G – A
