Chopin's harmonic innovations may have arisen partly from his keyboard improvisation technique. Temperley says that in his works "novel harmonic effects frequently result from the combination of ordinary appoggiaturas or passing notes with melodic figures of accompaniment", and cadences are delayed by the use of chords outside the home key (neapolitan sixths and diminished sevenths), or by sudden shifts to remote keys. Chord progressions sometimes anticipate the shifting tonality of later composers such as Claude Debussy, as does Chopin's use of modal harmony.

Who wrote about Chopin's "novel harmonic effects"?

In 1775, Patrick Henry delivered his famous "Give me Liberty or Give me Death" speech in St. John's Church in Richmond, crucial for deciding Virginia's participation in the First Continental Congress and setting the course for revolution and independence. On April 18, 1780, the state capital was moved from the colonial capital of Williamsburg to Richmond, to provide a more centralized location for Virginia's increasing westerly population, as well as to isolate the capital from British attack. The latter motive proved to be in vain, and in 1781, under the command of Benedict Arnold, Richmond was burned by British troops, causing Governor Thomas Jefferson to flee as the Virginia militia, led by Sampson Mathews, defended the city.

What did Patrick Henry's speech encourage to happen?
Answer: Virginia's participation in the First Continental Congress and setting the course for revolution and independence

In total, 156 prisoners have been either acquitted, or received pardons or commutations on the basis of possible innocence, between 1973 to 2015. Death penalty opponents often argue that this statistic shows how perilously close states have come to undertaking wrongful executions; proponents point out that the statistic refers only to those exonerated in law, and that the truly innocent may be a smaller number. Statistics likely understate the actual problem of wrongful convictions because once an execution has occurred there is often insufficient motivation and finance to keep a case open, and it becomes unlikely at that point that the miscarriage of justice will ever be exposed.

Between 1973 and 2015, how amny prisoners were acquitted or received pardons or commutations of their death sentences due to possible innocence?
