1. Miniatures as a musical form:
* No specific instrument: "Miniatures" as a musical form refers to short, concise musical pieces. They can be written for any instrument or ensemble, from solo piano to full orchestra. Famous examples include Chopin's nocturnes, Debussy's preludes, and Satie's Gymnopédies.
2. Miniatures as a painting technique:
* Not a musical term: "Miniatures" in this context refers to a specific painting technique where artists create extremely small and detailed artworks. This is not a musical term and is irrelevant to the question of instruments.
To clarify your question, please tell me what you mean by "miniatures" in the musical context.
