Apple made the wild decision to get rid of the classic startup chime in their newer MacBooks not so long ago. Many people were hit in the chest with the decision, some learned to live without it, but once you do hear the chime again when a Mac boots up, the nostalgia hits you way too hard. In fact, the chime has a greater effect on the newer MacBooks as you don't have to press the power button in order to boot into macOS. Just lift the lid and boom, the classic startup chime is there to embrace you.
Fun fact - the original startup chime was actually a C-major chord which then evolved into what we hear today. Basically what this means is that the pitch of the latest version of the chime is slightly higher than the older one, giving it a slightly more 'exciting' feel.
I highly recommend giving the Terminal command a go. Who knows it might just resonate with you, adding a little more joy to how you use your Mac for work or fun.
