One characteristic of the chanter is that it can produce staccato notes, because the piper seals it off at the bottom; with all of the finger holes closed, the chanter is silenced. This is also necessary for obtaining the second octave; the chanter must be closed and the bag pressure increased, and then fingered notes will sound in the second octave. A great range of different timbres can be achieved by varying the fingering of notes and also raising the chanter off the knee, which gives the uilleann pipes a degree of dynamic range not found in other forms of bagpipes. Pipers who use staccato fingering often are termed "closed-style" pipers. Those who use legato fingering more predominately are referred to as "open-style" pipers. Open piping has historical associations with musicians (often Irish travelling people) who played on the street or outdoors, since the open fingering is somewhat louder, especially with the chanter played off the knee (which can, however, lead to faulty pitch with the second octave notes).
