What was a notable development to the organ during the Baroque period?

During the Baroque period, one of the most significant developments regarding the organ was the addition of more stops, which allowed for greater tonal variety and expression. This enhancement enabled organists to produce a diverse palette of sounds by using different ranks of pipes, each with its unique timbre. The ability to control the mix of these different sounds afforded composers and performers greater freedom to explore musical texture and color within their works.

The increased number of stops meant that organ builders focused on crafting instruments that could deliver a broader range of dynamics and tonal qualities, which became essential in the context of Baroque music's emphasis on dramatic contrasts and intricate harmonies. This evolution in organ design was crucial for the music of the time, supporting complex compositions and the expressive style prevalent during the Baroque era.
