Music Theory


Do what makes you happy! If you don’t enjoy something, don’t do it! Embrace this if you want to play a song you love, write your own songs, or simply inflict mental anguish upon yourself.  The first few major chords are like the alphabet… if you want to play music, unfortunately, you have to force yourself into figuring them out first.

This for guitarists. If you want to play piano, go here

If you’re looking for some singing tips, drink warm water, because that’s the one of the few universally agreed upon words of wisdom, and go here!


The Official Guide to Reading Chords in Space


Greetings earthlings, below are the major Tom chords. These chord guides are all in Standard tuning read from left to right. The number corresponds to the fret. The 0 means the string is not fretted. The x means to mute the string by lightly pressing down on it, so it doesn’t make noise. 



Here are three of my favorite websites for figuring out how to play songs. Ultimate guitar  might be the most popular, but it’s inaccurate.

Open Tunings


Alternative tuning are like visiting a foreign country, they open up a whole new world of exploration. Nearly all slide guitarists play in open tunings. 

Here is standard tuning (Elephants And Donkeys Grow Big Ears) for comparison. On the left is your top string.


Standard   ~  EADGBE

Step Down  ~  D#G#C#F#A#D#

Dropped D  ~  DADGBE

Celtic (Dsus4) ~ DADGAD  

How to Create Any Chordal Tuning

For some reason, standard tuning is an 11 chord. Unless you play 11 chords all the time, which you don’t, it makes more sense to tune to a chord you use all the time.

You can create any tuning by tuning to the notes of the chord. If you play power chords most of the time, tune to a fifth chord by repeating the two notes in the chord. For example, the C5 chord is just notes C & G, so to tune to that tuning, tune all of your strings to C or G. If you want to tune to Csus4, you use the notes in that chord, so you would use the notes C,F, and G, tuning your strings to those notes. If the string tension gets too high, tune to a lower note, so you don’t snap a string. One tip is to change the frequency of your tuner from around 440 to around 430. This prevent breaks and will lower the sound of your guitar as a whole, giving it more bass.

The Major Chord Open Tunings 


Open A:    EAEAC#E

Open B:    BF#BF#BD#

Open C:    CGCGCE

Open D:    DADF#AD

Open E:    EBEG#BE 

Open F:    FACFCF 

Open G:    DGDGBD 

In open E, just strum for an E major. All of these work the same way. Bar your fingers across all the strings you will be playing a major chord. For example, in Open D, if you fret all the strings at the first fret it will be a D# major chord. In open D5(DADADD)the open strum will be a D5 chord, and the first fret barred, will be a D#5, second fret barred will be a E5, etc. Remember that between E & F and B & C, no sharps or flats exist. Likewise, if you capo the first fret of open E, you will be playing an F chord.

Diatonic Formula


Imaj IImin IIImin IVmaj V VImin VIImin (b5)

Or with seventh chords

Imaj7 IImin7 IIImin7 IVmaj7 V7 VImin7 VIImin7 (b5)

This can be used for any key.

Amaj7= Imaj7

Bmin7= IImin7



E7= V7

F#min7= VImin7

G#min7 (b5)= VIImin7 (b5)

These chords also fall under the categories Tonic,

Dominant and Subdominant.

Tonic chords provide a restful feeling.

The Tonic chords are Imaj, IIImin and VImin

Dominant chords provide a powerful feeling,

and like to resolve to the tonic chords.

The Dominant chords are V and VIImin(b5)

Sub-dominant chords provide a powerful feeling

as well but feel less of a need to resolve to the tonic.

The Subdominant (cadence) chords are IImin and IVmaj 

Below are three examples of key signatures, for the rest, you can get them by applying the diatonic formula.





Imaj  ❘   IImin  ❘   IIImin   ❘     IVmaj    ❘    V    ❘     VImin   ❘    VIImin (b5)

The scales were originally modes etched in stone tablets around Ancient Greece. 

 The major modes are Ionian, Lydian and Mixolydian. C Ionian is the C major scale. The Lydian mode has a # 4th scale note. Mixolydian mode has a flatted 7th.

 The minor modes are called Aeolian, Dorian and Phrygian. Aeolian is the same as natural minor, flat 3rd, 6th and 7th. Dorian is the same as Aeolian except with flats on just the 3rd and 7th.
