The last of Beethoven's quartets, the F Major (Op. 135), represents the last major work written by Beethoven. Only the revised finale to the Op. 130 quartet was written later than this work. This quartet is much smaller in scale than the other late quartets, but continues the personal impact of the work. Beethoven titled the fourth movement "Der schwer gefasste Entschluss" (The Difficult Resolution) and labled two of the primary motives "Muss es sein?" (Must it be?) and "Es muss sein " (It must be ).
