This research aims to present a harmonic and formal analysis of Op.27 No.1 G Minor string quartet by Edvard Hagerup Grieg who was a composer of the 19th century Scandinavian School and is regarded as the most important representative of Norwegian music. This movement, composed in sonata form, is embellished with romantic harmonies. Similarities and differences among various themes and how they are later developed are demonstrated through formal analysis. It is shown that the harmonic structure is formed by integration of tonality and modality. It is observed that the movement, even though mainly tonality dominated, phrygian and mixolydian modes are also used, albeit transposed to different keys to their originals. Chords formed with fourths are also used in some passages. It is important for young musicians who have chosen music as a career or others interested in music to some degree, to be knowledgeable about harmonic and formal structure of a composition. In depth knowledge of the piece of music played or listened to will have a positive impact on the quality of performing or appreciating it.
