At FL370 speed reduced for chop. During Power reduction; (Autothrottles on) Number 1 engine began a compressor stall. As per QRH; I disengaged Autothrottles and pulled engine back to stop the stall. First Officer immediately asked for lower. Speed started to decay; so I began descent prior to receiving a clearance for lower altitude. There was no traffic in the vicinity according to TCAS. Leveled at FL 330 and engine continued normal.Used 'ENGINE LIMIT OR SURGE OR STALL' procedure in QRH; Engine ran normally; so we continued to destination.
