What can you learn?
For now Sonid focuses on harmony within music theory and ear-training. This means that when you complete all classes you will know how to:
- Build and play any existing scale, from major to minor and from lydian to mixolydian.
- Recognize keys and progressions within a key.
- You can read any chord symbol and understand which notes and intervals are in it and which scale it uses, like: Dmaj7#11 or G13.
- Recognize intervals, chords, scales and progressions by ear. (only if selected ear-training)
Why would you learn music theory?
- Help your ears to play the right note or chord by understanding which progressions are in a certain key. Or which scale is to be played at a given moment in your song.
- Make your playing sound unique by using different versions of chords, or replace them altogether to give a change of colour in your voicings.
- Composing new melodies and chord progressions will never feel the same after completing the music theory lessons. Explore new realms of music harmonies and take your listeners on a fantastical journey.
- Let your fellow musicians know what you expect from them using the correct terminology creating an open and creative environment to let your songs grow more naturally.
- Find the right notes at the right time. Play your solo with passion and rejoice.
