What is the necessity of repeat in classical music?

I think repeat marks have a very useful function in musical scores.

For example, when transcribing a J-POP song, if you use repeat marks to skip the B melody and chorus to the A melody and the first chorus, you won't have to write the same score again.

Repeat marks are very common in classical music scores. In particular, music from the Baroque and Classical eras makes frequent use of repeat marks; for example, in Mozart's ``Turkish March,'' if you follow all the repeat marks faithfully, you end up playing almost two songs. Masu. However, this repeat symbol can actually be omitted when playing.

In the first place, the reason why repeat marks were so frequently used in the Baroque and Classical eras is that the recording media that we now take for granted did not exist, and it seems that a composer could basically only perform a piece once. The sonata form is the best example of this, and the repetition of the first theme by the reproduction section has a strong effect on the listener's heart.

On the other hand, it is not at all unusual for today's concerts to omit repeats. In competitions, the repeat mark loses its function due to the purpose of reducing the amount of time spent per person, or due to the individual interpretations of pianists and conductors. For beginner piano players, we want them to value the importance of ``playing according to the score,'' so we would like them to practice without omitting the repeat marks, but when it comes to concerts and competitions, please consult with your instructor. However, depending on the situation, you may choose not to repeat it.
