To make primary school music classes interesting, teachers need to use some innovative teaching methods and strategies. First of all, teachers can introduce new songs or music knowledge through storytelling, so that students can naturally be exposed to music while listening to stories. Secondly, teachers can design some interesting music games, such as "Musical Chairs", "Music Solitaire", etc., so that students can learn and enjoy music in the games. In addition, teachers can also encourage students to compose their own songs or choreograph, which will not only improve students' musical creativity, but also allow them to understand and feel music more deeply.

During the teaching process, teachers can also use multimedia teaching tools, such as music players, projectors, etc., to play some classic music works or music videos, so that students can learn music knowledge while enjoying them. At the same time, teachers can also organize some music activities, such as concerts, musicals, etc., to give students the opportunity to improve their music skills in practice.

Finally, teachers also need to pay attention to cultivating students' musical interests and hobbies, so that they can feel the charm of music while enjoying music. For example, teachers can recommend some music books or music movies suitable for primary school students, so that they can understand and like music while reading or watching.

In general, if primary school music classes are to be interesting, teachers need to carefully design and organize them so that students can learn and enjoy music in a relaxed and pleasant atmosphere.
