Description Especially for higher register playing, there can be a natural tendency to push the mouthpiece hard against the lips. Players know that more mouthpiece pressure can help to support weak or tired chops in order to continue playing. The downside is that too much pressure against the lips prevents proper blood flow, and wear out even faster. The Warburton A.P.E. helps learn how to maintain a high quality full-range buzz without applying excessive pressure.Key BenefitsBy learning how to reduce mouthpiece pressure against the lips will gain endurance.Sound quality will improve because 're also learning how to maintain the best quality buzz.Without the trumpet "in the way", can focus strictly on learning what mouthpiece angle and embouchure/aperture/lip set works best for - just by listening to the quality of the buzz.How does it work?It's easy to use - just plug mouthpiece into it and start buzzing in the lower range. Then increase the pitch of buzz as if playing a scale. As ascend higher up the scale will naturally start to press the mouthpiece harder against lips. The harder press, the more will compress the spring - which in turn will cause the air outlet to begin closing. If 're pressing too hard, the air outlet closes and the buzz stops because the air cannot escape.With practice will learn to ascend higher and higher up the scale without closing off the air escape. In order to keep the the A.P.E. working as smoothly, may find it helpful to occasionally clean any debris that might accumulate (pocket lint, etc) between the sliding pieces. A weak detergent solution followed by rinsing with water and drying with a lint free cloth will work fine for this cleaning.
