What Is History? belief in a hard core of historical facts existing objectively and independently of the interpretation of the historian is a preposterous fallacy, but one which it is very hard to eradicate. Carr maintained that there is such a vast quantity of information in the modern era that the historian always chooses the "facts" he or she decides to make use of. In Carr's famous example, he claimed that millions had crossed the Rubicon, but only Julius Caesar's crossing in 49 BC is declared noteworthy by historians. Carr divided facts into two categories: "facts of the past", that is historical information
Major thirds tuning of major-third and minor-sixth intervals are termed "inverse intervals" in the theory of music. Consequently, chord charts for minor-sixths tunings may be used for left-handed major-thirds tunings; conversely, chord charts for major-thirds tunings may be used for left-handed minor-sixths tunings. Major-thirds tuning facilitates playing chords with closed voicings. In contrast, standard tuning would require more hand-stretching to play closed-voice seventh chords, and so standard tuning uses open voicings for many four-note chords, for example of dominant seventh chords. By definition, a "dominant seventh" is a four-note chord combining a major chord and a minor seventh. For example, the C7 seventh
