Chords/ Arpeggios

Intro

Chords and arpeggios are almost the same thing. A chord is a group of notes that are played simultaneously. An Arpeggio is just a chord that is played one note at a time. When we play a chord one note at a time we have arpeggiated it.


Chord Construction

For the sake of memory chords can be broken into 5 families. These families are Major, Minor, Augmented, Diminished, and Synthetic. Listed below are 5 tables that show the chords of each family. Please note that these tables do not show all of the chords that exist. It is a vast outline of chords that are commonly perceived as "musical". Being able to recognize different chord types will give you a huge advantage as a musician.

In order to construct a chord we must be very familiar with our major and minor 3rd intervals. The reason for this is because most chords are built by stacking major and minor 3rds on top of one another. Notice that the C major chord below is made of a Major 3rd followed by a minor 3rd.

It is important to note that not all chords will be called the same thing by all people. It depends on the context they are being used in and also how the individual was taught. The more complex the chord the less established the name will be. Complex chords are usually named after the scale degrees that they contain.

When someone says that a chord progression is a I, vi, ii, V in the key of C, they are referring to those number triads in that key. In order to play a melody over that chord progression you would simply play the C major scale over top of it, while making up interesting rhythms and note combinations. If you wanted to be a little more complex you could play a different scale for each chord. You could do this by finding scales that correspond with each chord. This is a characteristic of Jazz. If you are playing a scale over a C Major chord then you would want to use a C scale that has the same notes that are contained in the C Major chord. These notes are of course C, E, and G. There are many scales that you can choose from or make up that are compatible with the C Major chord. C Ionian is just one example.

Chord Progressions

Chord progressions are a huge part of making music. The chords provide the backdrop of a piece of music. The melody is then played over top of the selected chord progression, This common practice for most Western Tonal music.

If you play a chordal instrument you should be able to construct chord progressions on your instrument. The cool thing about chordal instruments is that they can play both chords and melody, unlike some other instruments. Even if you play a non-chordal instrument it still helps to understand chord theory and chord progressions. Doing so will allow you to know what scales you should play when confronted with a certain chord progression. First let us use a reference key in order to determine the 7 different chords that are in a key. I will use C major for simplicity sake. Notice that the major chords have capital roman numerals and the minor chords are represented by lowercase roman numerals. This is standard practice in music theory.

C D E F G A B C

Chords I, IV, and V will always be Major in Major keys. Chords ii, iii, and vi will always be minor in Major keys. Chord vii will always be diminished in Major keys.

Nicely laid out info - clear and simple.

Just a typo correction though, augmented chords are 1 3 #5, not 1 #3 #5
