How do you choose the right instruments for a film score?

1 Know your genre

Different genres of film have different expectations and conventions when it comes to the musical style and instrumentation. For example, a horror film might use dissonant strings, percussion, and electronic sounds to create tension and fear, while a comedy might use light and upbeat instruments like piano, guitar, and woodwinds to create humor and fun. You should research and analyze the genre of your film, and see what kind of instruments are commonly used, and why. You can also experiment with subverting or mixing genres, but make sure you have a clear purpose and vision for doing so.

2 Consider your setting

The setting of your film can also influence the choice of instruments for your film score. The setting can include the location, time period, culture, and atmosphere of your film. For example, if your film is set in a medieval fantasy world, you might use instruments like harp, flute, lute, and drums to create a sense of magic and adventure. If your film is set in a futuristic dystopia, you might use instruments like synthesizers, electric guitars, and drum machines to create a sense of technology and oppression. You should consider how the instruments you use can reflect and enhance the setting of your film, and create a sense of immersion and authenticity.

3 Match your characters

Another factor to consider when choosing the instruments for your film score is the personality, motivation, and arc of your main characters. The instruments you use can help you express the character's emotions, traits, and goals, and show how they change and grow throughout the film. For example, if your protagonist is a rebellious and courageous hero, you might use instruments like brass, electric guitar, and drums to create a sense of power and action. If your antagonist is a cold and calculating villain, you might use instruments like piano, violin, and electronic sounds to create a sense of elegance and menace. You should think about how the instruments you use can create a musical theme or motif for your characters, and how they can interact and contrast with each other.

4 Balance your elements

One of the most important tips when choosing the instruments for your film score is to balance the different elements of your music, such as melody, harmony, rhythm, texture, and dynamics. You should avoid using too many or too few instruments, or making them too loud or too soft, or too simple or too complex. You should also avoid using instruments that clash or compete with each other, or with the dialogue and sound effects of your film. You should aim for a balanced and coherent musical score that supports and complements your film, without distracting or overpowering it.

5 Experiment and test

Finally, the best way to choose the right instruments for your film score is to experiment and test different options and combinations. You can use software, samples, or live musicians to create mock-ups or demos of your film score, and see how they work with your film. You can also get feedback from your collaborators, peers, or audience, and see how they react and respond to your music. You should be open to trying new and different instruments, and to revising and improving your film score, until you find the best fit for your film.
