This is Simple light sensitivity Metronome circuit. It use the transistor 2N3904 numbers and 2N3906 make to are origin frequency circuit. By the frequency in the sound from a loudspeaker will increase and is down. When lead light flasher come to near LDR within a darkroom. By resistance value of LDR be down when receive the light. Which will enhance the frequency of origin frequency sound circuit. By frequency change will continuously is like the wood keeps strokes the music there. The detail is other , see in the circuit.
