The question is why drums cannot express major or minor scales or chords,?
what makes it different than other musical instrument?
Drums absolutely have a pitch! So do cymbals (although cymbals have so many clashing frequencies it is harder to distinguish). So, all sounds have a pitch, although sometimes they have multiple pitches / overtones at the same time, creating lots of dissonance.
If you sample any sound and place it on a keyboard, you'll be able to hear the melodies. Even farts could be used, as I did in this video for a silly spooky kid's show... https://www.youtube.com/watch?v=WIDq8waQpWg
1. Drum sounds are typically quick sounds / transients. And we are not accustomed to listening to their pitch. A typical rock kit is not meant to be used harmonically in context. If a snare drum is tuned to D# and the song is in C Major, we probably don't even notice it. Sometimes a snare will have a lot of RING in it, and can be tuned for the specific song, so it won't clash.
2. Kick drums are so low that the pitch doesn't register as clearly for us. There's also a high "click" element to the kick, but that's also on the opposite extreme. It's such a high, short, click that we don't notice it.
3. Toms are the most obvious drum in a kit that have a pitch you can distinguish, along with the snare drum (especially when the snares are turned off). But these are also not meant to be relevant to the harmonic context. So long as the pitches don't distract or sound OUT.
4. Drums (or more broadly percussion instruments) that are meant to have an important pitch are called Pitched Percussion. You'll hear that all over the orchestra. Timpanis, etc. There's also a whole "sub-family" of instruments like Glockenspiel, Xylophone, Vibraphone, Tubular Bells, that are specifically meant for playing melodies.
As far as rock drummers, Terry Bozzio has set up gigantic drum kits all tuned to specific pitches / scales, as well as samples and midi triggers synced up with them. Personal trivia: Terry let me sit behind his kit and play around with that stuff one time in his studio.
Anyway, this is all to say that yes, percussion instruments can be (and are) used for melodies and chords!
