Pythagorean tuning is a system of musical tuning in which the frequency ratios of all intervals are based on the ratio 3:2. This ratio known as the "pure" perfect fifth, is chosen because it is one of the most consonant and easiest to tune by ear and because of importance attributed to the integer 3; as Novalis put it, "The musical proportions seem to me to be correct natural proportions." Alternatively, it can be described as the tuning of the syntonic temperament in which the generator is the ratio 3:2, ≈702 cents wide. The system had been attributed to Pythagoras by modern authors of music theory, while Ptolemy, Boethius, ascribed the division of the tetrachord by only two intervals, called "semitonium", "tonus", "tonus" in Latin, to Eratosthenes; the so-called "Pythagorean tuning" was used by musicians up to the beginning of the 16th century. "The Pythagorean system would appear to be ideal because of the purity of the fifths, but some consider other intervals the major third, to be so badly out of tune that major chords a dissonance."The Pythagorean scale is any scale which can be constructed from only pure perfect fifths and octaves.

In Greek music it was used to tune tetrachords and the twelve tone Pythagorean temperament was developed by medieval music theorists using the same method of tuning in perfect fifths, however there is no evidence that Pythagoras himself went beyond the tetrachord. A distinction can be made between a 12-tone Pythagorean temperament. Extended Pythagorean tuning corresponds 1-on-1 with western music notation and there is no limit to the number of fifths. In 12-tone Pythagorean temperament however one is limited by 12-tones per octave and one cannot play most music according to the Pythagorean system corresponding to the enharmonic notation, instead one finds that for instance the diminished sixth becomes a "wolf fifth". 12-tone Pythagorean temperament is based on a stack of intervals called perfect fifths, each tuned in the ratio 3:2, the next simplest ratio after 2:1. Starting from D for example, six other notes are produced by moving six times a ratio 3:2 up, the remaining ones by moving the same ratio down: E♭–B♭–F–C–G–D–A–E–B–F♯–C♯–G♯This succession of eleven 3:2 intervals spans across a wide range of frequency.

Since notes differing in frequency by a factor of 2 are given the same name, it is customary to divide or multiply the frequencies of some of these notes by 2 or by a power of 2. The purpose of this adjustment is to move the 12 notes within a smaller range of frequency, namely within the interval between the base note D and the D above it; this interval is called the basic octave. For instance, the A is tuned such that its frequency equals 3:2 times the frequency of D—if D is tuned to a frequency of 288 Hz A is tuned to 432 Hz; the E above A is tuned such that its frequency equals 3:2 times the frequency of A, or 9:4 times the frequency of D—with A at 432 Hz, this puts E at 648 Hz. Since this E is outside the above-mentioned basic octave, it is usual to halve its frequency to move it within the basic octave. Therefore, E is tuned to 324 Hz, a 9:8 above D; the B at 3:2 above that E is tuned to the ratio 27:16 and so on. Starting from the same point working the other way, G is tuned as 3:2 below D, which means that it is assigned a frequency equal to 2:3 times the frequency of D—with D at 288 Hz, this puts G at 192 Hz.

This frequency is doubled to bring it into the basic octave. When extending this tuning however, a problem arises: no stack of 3:2 intervals will fit into any stack of 2:1 intervals. For instance a stack such as this, obtained by adding one more note to the stack shown above A♭–E♭–B♭–F–C–G–D–A–E–B–F♯–C♯–G♯will be similar but not identical in size to a stack of 7 octaves. More it will be about a quarter of a semitone larger, called the Pythagorean comma. Thus, A ♭ and G ♯, when brought into the basic octave, will not coincide; the table below illustrates this, showing for each note in the basic octave the conventional name of the interval from D, the formula to compute its frequency ratio, its size in cents, the difference in cents between its size and the size of the corresponding one in the tempered scale. In the formulas, the ratios 3:2 or 2:3 represent an ascending or descending perfect fifth (i.e. an increase or decrease in frequency by a perfect fifth, while 2:1 or 1:2 represent an rising or lowering octave.

The major scale based on C, obtained from this tuning is: In equal temperament, pairs of enharmonic notes such as A♭ and G♯ are thought of as being the same note—however, as the above table indicates, in Pythagorean tuning they have different ratios with respect to D, which means they are at a different frequency. This discrepancy, of about 23.46 cents, or nearly one quarter of a semitone, is known as a Pythagorean comma. To get around this problem, Pythagorean tuning constructs only twelve notes as above, with eleven fifths between them. For example, one may use only the 12 notes from E♭ to G♯. This, as shown above, implies that only eleven just fifths are used to build the entire chromatic scale; the remaining interval is left badly out-of-tune, meaning that any music which combines those two notes is unplayable in this tuning. A out-of-tune interval such as this one is k

Batemans Bay is an open oceanic embayment, located in the South Coast region of New South Wales, Australia. The bay forms the mouth of the Clyde River and its primary outflow is to the Tasman Sea of the South Pacific Ocean. Batemans Bay is fed by the Clyde River and its tributaries, drawing its catchment from the eastern slopes of the Budawang Range and the Great Dividing Range from within the Budawang, Clyde River and Monga national parks. Cullendulla Creek flows into Batemans Bay, between the townships of Surfside and Longbeach, west of Square Head; the total catchment area of the bay is 28 square kilometres and the bay holds an estimated 383,484 megalitres of water at an average depth of 11.1 metres. The surface area of the bay comprises 34.5 square kilometres and stretches from the confluence of the Clyde River with the bay east of the town of Batemans Bay, near Snapper Island. The traditional custodians of the land surrounding Batemans Bay are the Indigenous Australian Yuin people of the Walbunja clan.

A number of sites surrounding the bay are considered culturally significant to the Aboriginal peoples. On 22 April 1770, European explorer, Captain James Cook first sighted the bay when navigating his way around Australia on his ship, HMS Endeavour. Cook may have named the bay in honour of Nathaniel Bateman. Alternatively, the name was chosen in honour of John Bateman, 2nd Viscount Bateman, a former Lord Commissioner of the Admiralty in the 1750s. List of lakes of Australia

Rizoupoli is a neighborhood of Athens, Greece. It is the northernmost neighborhood of Athens municipality along with the small district Probonas; the district is located between Patissia and Nea Philadelphia and is home to the Georgios Kamaras Stadium. Rizoupoli is named after Ioannis Rizopoulos, a businessman and land developer of the early 20th century. Rizopoulos's historic mansion stood in the area until 2002, when the Greek government agreed for its demolition. After the Asia Minor Catastrophe many refugees from Ionia and other places of Asia Minor settled in Rizoupoli. In 1948, the football stadium of Rizoupoli was built and became the home stadium of Apollon Smyrni, a historic club founded in Smyrni in 1891. A big cave with an area of 2,500 m2 is located in Rizoupoli, it is called Profitis Ilias. In the interior the cave, remains dating from the stone age have been found
