What is chord in music?
We have learned about scales in Scales Lesson. In this lesson we will learn about chords and relationship between chords and scales.
Music is based on a melody. Each song has a melody that characterize the sound. In order to enhance the feeling of a melody, we use chords to support the background. Chords are simply notes that are played at the same time. A Chord is composed of minimum two notes.
There is a relationship between the scale of the melody and the chords that can be used. Each scale has special chords which can be found very easily.
In the Scales Lesson, we gave an example (A major scale) and its respective notes. Here are the notes of A major scale.
A Major Scale
Each note has a respective chord. In order to find the notes in a chord, we can simply follow 1-3-5 pattern. First, third and the fifth notes can represent a chord. Below, click on notes to see their chords and

So, why chords get major, minor etc. endings?
It is all about the semitone differences between the notes. In Notes and frequency lesson, we have learned about the semitone distances between notes. In a chord, semitone differences between notes characterize the chord. However, we will not go into the details here. However, when you listen the chords in the Chords Page, pay attention to the happy mood of MAJOR chords and sad mood of MINOR chords.
So, when you create a melody and try to find chords to support it, try to use chords that has the note being played at the time. For example, if you are using A Major Scale and you want to play a chord when you play a D note at the melody, you can try Bm, D, G#dim chords, all of which has D note.
