This is the right structure of your code :)

learn more querySelectorAll

tips

avoid using var
when you start javaScript project line 1 you can apply use strict mode on,

'use strict';

let drumlenght = document.querySelectorAll('.drum').length;

for (let i = 0; i < drumlenght; i++) {
  document.querySelectorAll('.drum')[i].addEventListener('click', function () {
    alert('hi');
  });
}
