"The concept is basically; that the pieces we know and love are made up of scales, arpeggios, and the like"

This quote by Lara St. John is describing the fundamentals of music theory. She is saying that the pieces of music we enjoy are made up of scales, arpeggios, and other musical elements. Scales are a series of notes that rise or come down in a particular order. Arpeggios are a type of broken chord, where the notes of a chord are played in succession rather than all at once. These 2 aspects are the building blocks of music, and are used to create tunes, harmonies, and rhythms. Understanding how to use scales and arpeggios is necessary for any musician, as they are the foundation of all music. By comprehending the essentials of music theory, artists can develop lovely pieces of music that will be delighted in by many.
