Commands for sounds

[RodaballoXD]

So I know you can set the pitch of a sond typing a number in chat, but I don't know how to change the volume and I don't want to use set variable all time. Is there any way to set a sound's volume with commands?

I think you can do /sound volume <number>
OR
hold the sound and type in chat:
<Pitch> <Volume>

so hold the sound and type
1 0.5

to get a sound with pitch 1 and volume 0.5
