Information:  - 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.  - Orestis Makris ( Greek :   ; September 30 , 1898 -- January 29 , 1975 ) was a Greek actor and tenor . He graduated from the Greek Odeum of Athens and first entered the scene as a tenor in the troupe of Rosalia Nika in 1925 . He later joined the Papaioannou troupe , before moving to more comedic roles . Makris excelled in the portrayal of folk characters , especially the stock role of the `` drunkard '' . Makris also participated in about forty movies , mostly as an over-strict father . He is considered one of the most significant modern Greek actors . He was decorated with the Order of the Phoenix . He died on January 29 , 1975 in Athens and is buried at the First Cemetery in a family grave .  - 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.  - Spinto (from Italian, "pushed") is a vocal term used to characterize a soprano or tenor voice of a weight between lyric and dramatic that is capable of handling large musical climaxes in opera at moderate intervals. (Sometimes the terms "lirico-spinto" or "jugendlich-dramatisch" are used to denote this category of voice.)  - 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.  - 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, an octave (: eighth) or perfect octave is the interval between one musical pitch and another with half or double its frequency. It is defined by ANSI as the unit of frequency level when the base of the logarithm is two. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical systems".
