There are many different approaches you can take to developing new musical concepts, and the best approach will depend on your specific interests and goals. Here are a few ideas to get you started:
Experiment with different musical scales and modes: Try using scales or modes that are less common in Western music, such as the Arabic maqam scales or the Japanese kumoi scale. You could also try creating your own scales by altering the intervals between the notes.
Combine different musical styles: Mix and match elements from different musical genres or cultures to create a new sound. For example, you could combine elements of reggae with heavy metal, or blend Indian classical music with electronic dance music.
Use unconventional instruments: Try using instruments that are not typically associated with a particular genre or culture, such as a theremin or a didgeridoo. You could also try creating your own instruments using unconventional materials or construction methods.
Explore new technologies: Technology has opened up many new possibilities for creating and manipulating sound. Try using software to manipulate audio in new ways, or explore the use of new technologies such as virtual reality or motion sensing to create interactive musical experiences.
Collaborate with other musicians: Working with other musicians can be a great way to bounce ideas off of each other and come up with new concepts. You could also try organizing a workshop or jam session to brainstorm ideas with a group of musicians.
Remember, the most important thing is to have fun and be open to experimentation. There is no one "right" way to develop new musical concepts, and the best ideas often come from unexpected places. The key is to keep an open mind and be willing to try new things.
