a quark is a fundamental constituent of matter
  G                      F            C
Observed in 1968 through deep elastic scatter.
   C                            C            F
We found that protons aren't as simple as we thought.
           G                            F         C
We thought they were solid particles but they are not.


   C                           C              F
Protons in fact are made up of three separate pieces.
   G                               F         C
It just gets more confusing as our knowledge increases.
    C                               C          F
But that is what a quark is; It's a piece of a proton,
         G                         F             C
And they also make up other things including the neutron.


    C                       C      F
Oh, up, down, strange, charm, top, bottom
       G                                    F                C
If you don't know what a quark is, it don't matter you still got 'em.
         C                   C                  F
And with leptons and bosons, unless something's amiss,
             G                              F            C
They make up everything that we can see and that we know exists.


C                                  C              F
Things made up of quarks including protons and neutrons
G                            F               C
Are composite particles that physicists call hadrons.
C                             C           F
Many types of hadrons are theoretically described,
    G                        F                C
But most exist for only very brief amounts of time.


C                                  C                F
Quarks have electric charge, color charge, mass and spin,
    G                              F            C
And having color charge means they exist solely inside of
C                            C            F
Other kinds of particles and cannot exist alone.
         G                                 F         C
Which is why quarks have never been studied on their own.


C                       C      F
Up, down, strange, charm, top, bottom
       G                                    F                C
If you don't know what a quark is, it don't matter you still got 'em.
         C                   C                  F
And with leptons and bosons, unless something's amiss,
             G                              F            C
They make up everything that we can see and that we know exists.


C                              C          F
Quarks can join together in two different ways,
G                            F         C
Baryons and Mesons, but most instantly decay.
     C                                  C       F
If a particle has three quarks, then it's a baryon,
           G                                  F          C
If there's one quark and and anti-quark, then it is a meson.
      C                                 C           F
These tiny bits of matter are a part of almost everything
          G                       F               C
And there is no unified theory to make it less confusing.
        C                               C             F
But the fact that we've identified that they exist at all
   G                           F             C
Is so god damn remarkable that I just sit in awe.


    C                       C      F
Oh, up, down, strange, charm, top, bottom
       G                                    F                C
If you don't know what a quark is, it don't matter you still got 'em.
         C                   C                  F
And with leptons and bosons, unless something's amiss,
             G                              F            C
They make up everything that we can see and that we know exists.
