Although symphony and concert are both important forms of music performance, there are some obvious differences between them.

1. Music performance form: A symphony is a classification of musical works that is performed by an orchestra and includes multiple different movements. A concert is a form of music performance, which can include symphony music performances.

2. Performance venue and scale: Symphony performances are performed in specialized concert halls, theaters or large performance venues, while concerts vary in scale and can be held in small concert halls.

In addition, symphonies and concerts will also differ in performance content, appeal and feelings to the audience due to differences in specific musical works and performers. For example, folk music and symphony are two different musical styles. Although there are similarities between them, there are also differences in many aspects.
