This is the most common type of saxophone for beginners due to its manageable size and mid-range sound. It's likely the type offered by MegArya.
There's no confirmation on the material used. Beginner saxophones are typically made of lacquered brass for durability and affordability.
The lacquer finish could be gold (like the B-flat model) or silver (common for beginner saxophones). Lacquer offers a shiny appearance but can show wear and tear more easily.
The number of keys will likely depend on the model (professional vs. beginner). Beginner saxophones typically have around 17-19 keys, while professional models may have more for additional range and fingering options.
Depending on the specific package, it might include a mouthpiece, ligature, reeds, cleaning cloth, and possibly a soft or hard case (soft cases offer basic protection, hard cases offer more security).
