When writing Middle C in music notation it is just below the stave when using the treble clef and just above the stave when using the bass clef. This is shown in the first and last notes of the musical example below. The Middle C sits on a ledger line (an extension of the stave written just for one note).
On the piano the Middle C key is C4.
When starting to learn the piano, most books make their easiest pieces start on Middle C. This is because the right hand can then play tunes using 5 notes (C to G) using white notes only (no sharps or flats). It is also easy to recognize Middle C in notation. It is also a help to find the correct place to sit at the piano (Middle C is opposite the player's "middle" (tummy)). One problem can be that young children learning the piano may think that all pieces start on Middle C. Pieces can start anywhere on the keyboard.
Middle C is the lowest note of the flute. It is a fairly low note for a child or woman to sing, but a fairly high note for a man to sing.
Middle C vibrates at 262Hz.
Principality
A principality (sometimes also called princedom) is a country which is ruled by a prince or princess. Principalities were common in the Middle Ages. Some principalities that still remain today are Andorra, Monaco and Liechtenstein. Examples of subnational principalities are Asturias (Spain).
Some states claim to be principalities but are not recognised by other countries: Sealand (a Sea Fort off the English coast), Seborga (a small town in Italy), the Principality of Hutt River in Australia and the Principality of Minerva in the Pacific. These states are examples of micronations.
Sometimes the word is also used to mean dependent territories in Africa, Asia and India, pre-Columbian America and Oceania. For these, the word princely states is generally preferred, especially if they came under the authority of a European colonial power.
Vlad III the Impaler
Vlad III, Prince of Wallachia, is more commonly known as Vlad "Țepeș" (the Impaler) . He was born in Segesvár, Transylvania, - then under the control of the Kingdom of Hungary - in 1431. He was the Prince of Wallachia and ruled there three times, in 1448, 1456–1462 and 1476.
In the English-speaking world, Vlad is best known for the legends of his cruelty. These legends gave Bram Stoker the idea for his main character in the popular "Dracula" novel.
Wallachia was placed between the Kingdom of Hungary and the Ottoman Empire. The Turks were fighting against the Kingdom of Hungary and this made Wallachia a battle ground between Turks and Hungarians. The rulers of Wallachia were chosen by the Romanian aristocrats, called boyars. The ruler was often from a noble house, sometimes an illegitimate prince born outside of marriage. The country rulers were struggling with each other, and this was resulting in instability, family disputes and murders.
Vlad the Impaler was born in 1431. His father was Vlad II Dracul. His mother is unknown. Vlad II was married to princess Cneajna of Moldavia. He had several mistresses. Vlad III was raised by Cneajna with the help of her household. He had two brothers, Mircea born c. 1430 and Radu born 1435. He also had a half-brother, Vlad the Monk born around 1425-1430.
Vlad II went to the court of Holy Roman Emperor, Sigismund of Luxemburg as a young man. Sigismund was supporting Vlad II for the throne of Wallachia, and made Vlad II knight 1431 of the Order of the Dragon ("Societas Draconis" in Latin).
The oldest brother, probably named Mircea, was sent by Vlad II to fight the war against the Turks in 1444. This war called the Battle of Varna was lost. Mircea and his father died in 1447.
Vlad's half-brother. Vlad the Monk was waiting in Transylvania for a chance to rule Wallachia. Vlad the Monk was a monk until he became prince of Wallachia in 1482.
Radu, known as Radu III the Fair or Radu the Handsome, the youngest brother, was also Vlad’s most important rival as he continuously tried to replace Vlad on the throne.
From his first marriage, Vlad the Impaler (or Vlad III) had a son, later prince of Wallachia, as Mihnea the Evil. His first wife, whose name we do not know, died during the war 1462. Vlad III the Impaler was fighting against the Turks. The legend says that the Turkish army surrounded Vlad's castle, the Poienari Castle, led by his brother Radu the Handsome. Vlad's wife threw herself off the tower into the Argeş River below the castle. According to legend she remarked that she "would rather have her body be eaten by the fish of the Argeş than be captured by the Turks."
Vlad had another two sons with his second wife Ilona Szilágyi a fraternal cousin of King Matthias Corvinus of Hungary. Some historians strongly believe they may have also had a daughter named Maria Zaleska (Princess Zaleska).
Vlad was very likely born in the city of Sighişoara in Transylvania, then a part of the Kingdom of Hungary, during the winter of 1431. Sighişoara was a military fortress at that time. He was born as the second son to his father Vlad Dracul. He had an older brother, Mircea, and a younger brother, Radu the Handsome. Although his native country was Wallachia, the family lived in exile in Transylvania because his father had been chased away by pro-Ottoman boyars.
Vlad's father was pressured by the (Turkish) Ottoman sultan. He gave a promise to be the vassal of the Sultan and gave up his two younger sons as hostages so that he would keep his promise.
Vlad suffered much at the hands of the Ottomans, and was locked up in an underground prison; however, his younger brother, Radu, caught the eye of the sultan's son. Radu was released and converted to Islam, and he was allowed into the Ottoman royal court.
These years had a great influence on Vlad. They shaped Vlad's character. He was often whipped and beaten by the Turks for being stubborn and rude. He developed a well-known hatred for Radu and for Mehmed, who would later become the sultan.
Vlad's father and Vlad's older brother, Mircea, were dead at this point. The Turks invaded Wallachia and the Sultan put Vlad III on the throne as his puppet ruler. His rule at this time was short; Hunyadi invaded Wallachia and chased him away the same year. Vlad fled to Moldavia and was put under the protection of his uncle, Bogdan II.
Bogdan was assassinated. Vlad took a chance and fled to Hungary. Impressed by Vlad's knowledge of the Ottoman Empire, Hunyadi pardoned him and took him in as an adviser. Later, Hunyadi made him the Kingdom of Hungary's candidate for the throne of Wallachia.
In 1456, Hungary invaded Serbia to chase away the Turks, and at the same time Vlad III invaded Wallachia. Both invasions were successful. Hunyadi suddenly died of the plague. Vlad became prince of Wallachia.
Vlad was spending most of his time at the court of the city of Târgovişte. He made laws, met foreign ambassadors, judged in trials. He reinforced some castles and probably enjoyed hunting with his friends.
The constant state of war since the death of his grandfather, Mircea the Elder, in 1418, led to increased crime levels and less agricultural production. Trade had almost disappeared in Wallachia.
Vlad tried to solve these problems with severe methods. He needed an economically stable country.
Vlad wanted to eliminate all threats to his power, mainly the rival nobility groups, such as the boyars. This was done mainly by killing them and reducing the their economic role. The Wallachian nobility had connections with the Saxon merchants. The Saxons lived in the free towns of Transylvania, making trade flourish. Vlad cut their towns trade privileges with Wallachia, and started war against them.
Vlad gave key positions in the Prince’s Council to people of lower rank who were loyal to him. Vlad preferred to knight men from the free peasants.
