Analyzing the Compositional Characteristics and Performance Techniques of Mozart's Flute Concerto in G Major in the Classical Period: Taking the First Movement as an Example

Wolfgang Amadeus Mozart (1756.1.271791.12.5) was one of the most outstanding composers of the Classical period. His works are characterised by rigorous structure, clear harmonic function, and extensive use of homophonic texture. This paper examines the first movement of the Flute Concerto in G Major as a classic example, systematically analysing its compositional features and performance techniques to reveal the classical period's musical paradigms as manifested in this work and to identify the key technical challenges in its performance. The paper employs documentary research to trace the work's compositional development and score analysis to conduct a detailed examination of its melody, harmony, and orchestration. The research found that by comparing multiple performance versions, it was revealed that the core of modern performance of this work lies not only in solid performance skills but also in a deep understanding of the emotional expression methods of the Classical period, which has positive significance for the expressiveness of modern flute performance.
