There is a feeling of use. The NY series has a different rim shape from the Symphony series, and is characterized by a mouthfeel that wraps around the lips. It feels similar to a Bach 4G, but the smooth rim shape eliminates any feeling of tightness, allowing for a more open and free blowing experience, with more overtones and a warmer tone. Shifting is also easier, and you can become stronger in leaping (slurred) phrases. The NY series becomes deeper as the number increases, but this individual is slightly deeper than a 5G, requiring more air, but allowing you to play with a richer tone.
