The Associated Board of the Royal Schools of Music provides international, comprehensive examinations that score based on musical qualifications and assessments. All eight levels of the ABRSM have the same four characteristics: set pieces, scales, sight reading, and aural.
Learning scales and arpeggios helps you to develop reliable muscle memory for common finger movements and to improve your tone control across the full note range. It also helps you to improve your pitch and interval awareness, and to become familiar with keys and their related patterns. It also helps to build an understanding of keys, which gives you confidence when sight-reading, learning new pieces, and performing. You can also develop many aspects of technique through scales practice, including familiarity with the physicality of your instrument.
