Why learn music theory?
Help your ears play music.
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 variations of what is to be expected by altering modes. Play moll-dur on the fourth grade or a dominant chord on the third.
Play beautiful melodies in any key.
Find the right notes at the right time. Build your solo up from the ground exactly how you feel it at the moment with passion and rejoice. From the most basic C major and A minor keys to church modes like G dorian or F lydian and altered scales like D mixolydian #11 your phrasing will be spot on.
Use chord substitutes and inversions.
Make your playing sound unique by using different versions of chords, or replace them altogether to give a change of colour in your voicings. Substitute Fmaj7 with Dm9 or play an inspiring Amaj9#11 instead of B7 to sound genuine and in control of your instrument.
Write the most compelling songs.
Composing new melodies and chord progressions will never feel the same after completing the music theory lessons. Express your emotions just the way you want them. Explore new realms of music harmonies and take your listeners on a fantastical journey.
Communicate with musicians.
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.
