Circuit Explination

The main concept of this circuit is changing the tone of the sound by changing the frequency. The frequency value is dependent mainly on the values of resistors and capacitor as shown in this equation:

Frequency (f) = 1.44 / ( (R1 + 2 * R2) x C1 )

we can replace the value of R1 (Mostly it is 1K ohm) then set the value of C1 (Mostly 100nf) and rearrange the equation to calculate the required value of R2 to get the required frequencies

Frequency (f) = 1.44 / ( (1000 + 2 * R2) x 10-7 )
Resistance (R2) = ( ( 1.44 x 107 ) / f ) - 500

Build Circuit on TinkerCad

I started to put my components to build the circuit, as mentioned the output depends manily of the values of R6 1Kohm , R5 6.2Kohm and c1 100nf .Also,the values of other resistors strting from the right to left which are 390 ohm ,910 ohm,1Kohm,1.1kohm,620 ohm,1.3K ohm

the final circuit is shown in the below photo
