user: Please answer the following question: Information:  - Vocal range is the measure of the breadth of pitches that a human voice can phonate. Although the study of vocal range has little practical application in terms of speech, it is a topic of study within linguistics, phonetics, and speech and language pathology, particularly in relation to the study of tonal languages and certain types of vocal disorders. However, the most common application of the term "vocal range" is within the context of singing, where it is used as one of the major defining characteristics for classifying singing voices into groups known as voice types.  - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state.  - Slovenia, officially the Republic of Slovenia (Slovene: , abbr.: "RS"), is a nation state in southern Central Europe, located at the crossroads of main European cultural and trade routes. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and the Adriatic Sea to the southwest. It covers and has a population of 2.06 million. It is a parliamentary republic and a member of the United Nations, European Union, and NATO. The capital and largest city is Ljubljana.  - A baritone is a type of classical male singing voice whose vocal range lies between the bass and the tenor voice types. It is the most common male voice. Originally from the Greek , meaning "deep (or heavy) sounding", music for this voice is typically written in the range from the second F below middle C to the F above middle C (i.e. FF) in choral music, and from the second A below middle C to the A above middle C (A to A) in operatic music, but can be extended at either end. The baritone voice type is generally divided into the baryton-Martin baritone (light baritone), lyric baritone, "Kavalierbariton", Verdi baritone, dramatic baritone, "baryton-noble" baritone, and the bass-baritone.  - Vatican City , officially Vatican City State or the State of Vatican City, is a walled enclave within the city of Rome. With an area of approximately 44 hectares (110 acres), and a population of 842, it is the smallest State in the world by both area and population, but formally it is not sovereign, sovereignty being held by the Holy See, the only entity of public international law that has diplomatic relations with almost every country in the world.  - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux.  - A voice type is a particular human singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points ("passaggio"), such as breaks and lifts within the voice. Other considerations are physical characteristics, speech level, scientific testing, and vocal register. A singer's voice type is identified by a process known as voice classification, by which the human voice is evaluated and thereby designated into a particular voice type. The discipline of voice classification developed within European classical music and is not generally applicable to other forms of singing. Voice classification is often used within opera to associate possible roles with potential voices. Several different voice classification systems are available to identify voice types, including the German "Fach" system and the choral music system among many others; no system is universally applied or accepted.  - Modal voice is the vocal register used most frequently in speech and singing in most languages. It is also the term used in linguistics for the most common phonation of vowels. The term "modal" refers to the resonant mode of vocal cords; that is, the optimal combination of airflow and glottal tension that yields maximum vibration.  - A sopranist (also, sopranista or male soprano) is a male singer who is able to sing in the vocal tessitura of a soprano usually through the use of falsetto vocal production. This voice type is a specific kind of countertenor. In rare cases an adult man may be able to sing in the soprano range using his normal or modal voice and not falsetto due to endocrinological reasons, like Radu Marian, or as a result of a larynx that has not completely developed as in the case of Michael Maniaci.  - MILAN ("milan(e)" is French for kite) is a European anti-tank guided missile. Design of the MILAN started in 1962, it was ready for trials in 1971, and was accepted for service in 1972. It is a wire guided SACLOS (semi-automatic command to line-of-sight) missile, which means the sight of the launch unit has to be aimed at the target to guide the missile. The MILAN can be equipped with a MIRA or MILIS thermal sight to give it night-firing ability.  - Singing is the act of producing musical sounds with the voice, and augments regular speech by the use of sustained tonality, rhythm, and a variety of vocal techniques. A person who sings is called a singer or vocalist. Singers perform music (arias, recitatives, songs, etc.) that can be sung with or without accompaniment by musical instruments. Singing is often done in an ensemble of musicians, such as a choir of singers or a band of instrumentalists. Singers may perform as soloists, or accompanied by anything from a single instrument (as in art song or some jazz styles) up to a symphony orchestra or big band. Different singing styles include art music such as opera and Chinese opera, religious music styles such as gospel, traditional music styles, world music, jazz, blues and popular music styles such as pop and rock.  - In music, tessitura ("texture") is the most musically acceptable and comfortable vocal range for a given singer or, less frequently, musical instrument; the range in which a given type of voice presents its best-sounding texture or timbre. This broad definition is often interpreted to refer specifically to the pitch range that most frequently occurs within a given piece, or part, of music. For example, throughout the entirety of Wagner's "Ring", the music written for the role of Siegfried ranges from C to C, but the tessitura is described as high because the phrases are most often in the range of C to A.  - Angelo Manzotti is an Italian countertenor or sopranist born in 1971 in Marmirolo , Italy . He began singing in the falsetto register at the age of twelve . He studied at the Accademia Rossiniana in Pesaro and made his debut in August 1989 at the Rossini Opera Festival there . After perfecting his technique with Rodolfo Celletti , he won the 1992 `` Luciano Pavarotti '' International Competition in Philadelphia . He has developed a special technique where only the front parts of the vocal cords vibrate , and in this way , he is able to avoid having to use the falsetto , obtaining a clear voice , remarkably similar to a woman 's voice . His first recording , Arie di Farinelli ( Bongiovanni , 1995 ) , was awarded the `` Timbre de Platine '' by Opéra International .  - Marmirolo is a "comune" (municipality) in the Province of Mantua in the Italian region Lombardy, located about east of Milan and about northwest of Mantua. Its territory, which is totally plain as part of the Pianura Padana, is crossed by the Mincio river.  - The euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also officially used by the institutions of the European Union and four other European countries, as well as unilaterally by two others, and is consequently used daily by some 337 million Europeans . Outside of Europe, a number of overseas territories of EU members also use the euro as their currency.  - Michael Maniaci (born in 1976) is an American opera singer. Possessing a male soprano voice, Maniaci is noted for his claim to be able to sing into the upper soprano register without using falsetto, an otherwise common phonation for men who sing in high registers, such as countertenors. Although this was possible for castrati, because of the hormonal imbalance following castration, Maniaci claims that, for some unknown reason, his larynx did not develop and lengthen completely, causing his voice not to "break" in the usual manner. This physical particularity has given Maniaci the ability to sing in the soprano register without sounding like a typical countertenor or a female singer. For this reason, professional vocal pedagogists consider Maniaci's voice to be unique among countertenors, and compare his vocal quality to the castrato voice of the past.  - A parliamentary republic is a republic that operates under a parliamentary system of government where the executive branch (the government) derives its legitimacy from and is accountable to the legislature (the parliament). There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power, much like constitutional monarchies. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary power.  - A countertenor is a type of classical male singing voice whose vocal range is equivalent to that of the female contralto or mezzo-soprano voice types. The countertenor range is generally equivalent to a contralto range, extending from around G to D or E, although a sopranist (a specific kind of countertenor) may match the soprano's range of around C to C. Countertenors often are baritones or tenors at core, but rarely use this vocal range in performance. The countertenor voice type has a lower tessitura than the contralto or mezzo-soprano.  - A boot is a type of footwear and a specific type of shoe. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. Traditionally made of leather or rubber, modern boots are made from a variety of materials. Boots are worn both for their functionality  protecting the foot and leg from water, extreme cold, mud or hazards (e.g., work boots may protect wearers from chemicals or use a steel toe) or providing additional ankle support for strenuous activities with added traction requirements (e.g., hiking)  and for reasons of style and fashion.  - Tenor is a type of classical male singing voice whose vocal range is one of the highest of the male voice types. The tenor's vocal range (in choral music) lies between C, the C one octave below middle C, and A, the A above middle C. In solo work, this range extends up to C, or "tenor high C". The low extreme for tenors is roughly A (two As below middle C). At the highest extreme, some tenors can sing up to two Fs above middle C (F). The tenor voice type is generally divided into the "leggero" tenor, lyric tenor, spinto tenor, dramatic tenor, heldentenor, and tenor buffo or spieltenor.
