If we want to be a producer,This circuit would be a good starting point to composed music for 1000 tracks.

As Figure 1 is a common circuit. Which will see them always when use LED running. We will use an IC-555 timer and IC-4017 Decade Counter Divider with 10 Decoded as sound effect generator with adjusting tone music with a tempo slow – fast as you want it to VR11. And VR1-VR10 to adjust the tone according to need more than 1000 tone.

Figure 1 is the simple sound effect generator circuit using IC-555 and IC-4017

This circuit can be used as an various alarms. We will see that use a lot of a variable resistors or potentiometers. But it’s better than using a fixed value resistor then got bored listening to only 2-3 times. The value of VR1-VR10 will use no more than 100K. Because if it more than this will cause IC3 generate the frequency is lower than 100Hz which we will listen don’t as music.
