At this level you will study more complex keys and time signatures, such as scales (major, minor harmonic and minor melodic) with up to five flats/sharps in them, and all regular simple and compound time signatures, including more obscure ones such as 9/16, as well as more advanced rhythmic tools such as triplets and duplets. You'll also learn the chromatic scales.
This grade covers the tonic, dominant and subdominant chords, and intervals between any two notes (major, minor, perfect, augmented and diminished).
You'll learn how to read the alto clef (used by the viola) as well as lots of other facts about the standard orchestral instruments.
Please note that the grade 4 course/syllabus overlaps with grade 3, so we will also review some topics from grade 3 (those that normally cause the most confusion!)
