In junior high school music classes, there are many suitable interactive methods that can increase student participation and interest. The following are some common interactive methods:

1. Chorus and ensemble: Let students divide into groups or the whole class to sing or sing a song together. This improves students' collaboration and musical skills.

2. Create songs: Encourage students to compose their own songs or lyrics. You can provide them with some themes or inspiration for them to be creative.

3. Music games: Use music games to make the classroom more interesting. For example, let students guess the name of a song or the artist by listening to music, or have a music knowledge contest.

4. Role play: Let students play different roles, such as musicians, composers or conductors, and understand the historical and cultural background of music through simulated performances.

5. Music performance: Arrange students to perform music performances, which can be solo, solo or band performances. This can improve students' self-confidence and expression skills.

6. Music production: Let students use music production software or musical instruments to produce their own music works. This develops their creativity and technical abilities.

7. Music discussion: Guide students to conduct music discussions and let them share their feelings and understanding of music. Some questions can be asked to allow students to think and express their opinions.

8. Music competition: Organize music competitions to allow students to showcase their talents and skills. Different awards can be set up to stimulate students' sense of competition and enthusiasm.

The above are some interactive methods suitable for junior high school music classes, which can be selected and adjusted according to students' interests and abilities. Through these interactive methods, students' interest in music can be stimulated and their learning effectiveness and participation can be improved.
