Accompaniment: The orchestra provides accompaniment to the soloist, ensuring that the soloist's voice or instrument stands out prominently. The orchestra follows the soloist's lead, providing support and complementing the soloist's performance.
Playing cues: The orchestra typically plays cues or interludes that lead into and out of the soloist's sections. These cues help transition smoothly between the soloist's performance and the orchestral parts.
Dynamic control: The orchestra adjusts its dynamics to match the soloist's expression. For example, if the soloist is playing a soft passage, the orchestra will lower its volume to create a contrasting effect. Conversely, if the soloist is playing a loud section, the orchestra may play louder to bolster the overall intensity of the music.
Balancing the sound: The orchestra members must balance their sound with the soloist's performance. They must avoid overpowering the soloist while still providing adequate support. This requires careful attention to dynamics, articulation, and phrasing.
Ensemble playing: Despite reducing their playing, the orchestra still maintains ensemble cohesion and unity. The orchestra members must listen to each other and adjust their playing to blend harmoniously with the soloist.
Following the conductor: The conductor plays a crucial role in coordinating the orchestra during a solo performance. The conductor cues the orchestra for when to enter and exit, ensuring they are synchronized with the soloist.
