Chord selection is the process of selecting chords to accompany a melody or bassline. It is an important part of music theory and composition, as the chords you choose can greatly affect the sound and feel of your music. There are many different factors to consider when choosing chords, including the key of the song, the mood you want to create, and the overall style of the music.
The most important factor to consider when choosing chords is the key of the song. The key is the tonal center of the song, and all of the chords you choose should be related to the key. There are many different ways to determine the key of a song, but the most common method is to look at the last chord in the song. The last chord is usually the tonic chord, which is the chord that gives the song its tonal center. Once you know the key of the song, you can start to choose chords that are related to the key. There are many different types of chords, but the most common types are major chords, minor chords, and seventh chords. Major chords are bright and happy sounding, while minor chords are darker and more somber sounding. Seventh chords are more complex than major and minor chords, and they can add a lot of interest and depth to your music.
