Wooden sopranino recorder in the key of F that is made of softer castello wood with a beautiful warm tone is good for expressing subtle musical nuances. Though it is not technically a boxwood, it is commonly referred to as "Castello Boxwood". The instrument features a Baroque key system and an arched windway that has a slight resistance when played for better breath control which gives greater tonal expressivity and projection. A cotton case, a fingering chart, cork grease and a cleaning rod are included.
