Which composer is known for large orchestrations and a vast scope of sound?

The composer recognized for large orchestrations and a vast scope of sound is Mahler. His symphonic works are characterized by their expansive structures, rich harmonies, and a wide range of emotional depth. Mahler often integrated vast orchestras, including expanded brass and woodwind sections, percussion, and even vocal elements in his symphonies, which allowed him to create a powerful and immersive listening experience.

His symphonies are notable for their dramatic contrasts and monumental proportions, capturing complex themes ranging from existential despair to exuberant joy. Mahler's ability to blend symphonic and operatic elements, alongside his innovative use of orchestration, set him apart from composers like Debussy and Bach, who, while also significant in their contributions to music, did not focus on the same large-scale orchestral textures and emotional breadth found in Mahler's works.
