    3.1.2 “start sound” block
                      This block also chooses the sound and then play it, but not stops the next script. It

                      plays the sound with the next script but sound will overlap with next sound, so, we
                      have to use the “wait for 1 seconds” block from the control block if we want to play
                      the next sound.

                                        Aryan: OK! Wow, It means sprite can play the sounds now. But could we increase
                                        or decrease the volume of the sound also.

                         Gowri: Yes, dear! We can also change the intensity or volume of the sound also,
                         as we did in our Laptops or in TVs. Let’s learn it now with the following 2 options:

                      3.1.3 “change volume by…%” block

                      This block is used to increase or decrease the volume of sound by a particular value.
                      If value is a +ve number then sound will increase and when value is a -ve number then
                      sound will decrease.

                      3.1.4 “set volume to…” block

                      This block is used to set the volume of sound to a particular value.

                         Aryan: OK! But could we increase or decrease the speed of the sound also.
                         Gowri: Yes, dear! We can also change the speed of the sound, as we did in some videos. Let’s
                         learn it now with the help of the following 2 options:-

                      3.1.5 “change…effect by…” block
                      This block has a drop-down menu; we can choose one option out of two options: pitch

                      and pan left/right.

                      3.1.5.1 “change pitch effect by…” block (means when pitch is selected),
                      It means speed or pitch of the sound changes by a value which we will give. If the

                      value is +ve means, pitch of the sound is increasing and if the value is -ve means pitch
                      of the sound is decreasing. (max. value for pitch can be 360 and minimum can be -360).

                      3.1.5.2   “change pan left/right effect by…” block (means when pan left/right
                                  is selected),

                      This option is used to play the sound in earphones. It will change the side of the
                      sound from where sound is played. If the value is +ve, it means the sound will play

                      more from right ear. If the value is -ve, it means the sound will play more from left
                      ear.  If the value is 0, it means the sound will play normal. If the value is -100, it
                      means the sound plays completely in the left ear and if value is +100, it means the
                      sound plays completely in the right ear in headphones.
