In music, an alto clef is the counter-tenor clef, or the C clef, placed so that the two strokes include the middle line of the staff. Research Alto Clef
In music, C is the keynote of the normal or natural scale, which has neither flats nor sharps in its signature. It is also, the third note of the relative minor scale of the same. C after the clef is the mark of common time, in which each measure is a semi-breve.
In music, a clef is a sign placed at the beginning of a stave to indicate the pitch and name of notes. There are now only three clefs in use: the treble or G clef; the base or F clef; and the C clef. The G clef consists of the five highest lines, the F clef of the five lowest lines, of the great stave. The C clef may have three positions. It may be placed upon the first or lower line of the staff, in which case it is called soprano clef, upon the third line, in which case it called alto clef, or upon the fourth line, in which case tenor clef. It rarely or never is placed upon the second line, except in ancient music. Research Clef
In music, counter tenor or countertenor is one of the middle parts between the tenor and the treble, that is a high tenor. It is the highest male adult voice, having its easy compass from tenor G to treble C, and music for it is written on the alto or C clef on the middle line of the staff. The lowest voices of females and boys have about the same register, and are sometimes inaccurately called counter tenor. The correct term is alto or contralto. Research Counter Tenor
The ophicleide was a brass wind instrument, now replaced by the brasstuba, developed about the beginning of the 19th century from an ancient wind instrument called the serpent. It had a bell bottom, conical tube, and cupped mouthpiece, and usually contained eleven keys. Alto and double- bass forms of the instrument were constructed: but it was usually set in C, and had its music written in the bass clef. Research Ophicleide
The piccolo is a small woodwind instrument of the flute family. It is played from the trebleclef, but its music is usually written an octave lower than the pitch of the sounds produced. Research Piccolo
In music a signature is the designation of the key (when not C major, or its relative, A minor) by means of one or more sharps or flats at the beginning of the staff, immediately after the clef, affecting all notes of the same letter throughout the piece or movement. Each minor key has the same signature as its relative major. Research Signature
