What are the different sizes of saxophones and how do they differ in terms of sound and playability?

There are four main sizes of saxophones: soprano, alto, tenor, and baritone. Each size produces a different range of tones, with the soprano being the highest and the baritone being the lowest. The smaller saxophones like the soprano and alto tend to have a brighter and more piercing sound, while the larger saxophones like the tenor and baritone have a deeper and richer tone. In terms of playability, the smaller saxophones are generally easier to handle and require less air to play, while the larger saxophones may be more challenging for beginners due to their size and weight.
