Tin whistle of which tone holes the player should cover. The most common format is a vertical column of six circles, with holes to be covered for a given note shown filled with black, and a plus sign (+) at the top for notes in the second octave. Tablature is most commonly found in tutorial books for beginners. The tonic solfa is found in Ireland and possibly Wales, especially in schools. Many schools have printed sheets with tunes notated in tonic solfa, although in Ireland more have teaching by note. With the availability of good standard notation tutor books, teaching is possibly
Tin whistle narrowing the lip/embouchure. Since the size and direction of the tin whistle's windway is fixed, like that of the recorder or fipple flute, it is necessary to increase the velocity of the air stream. (See overblowing). Fingering in the second register is generally the same as in the first/fundamental, though alternate fingerings are sometimes employed in the higher end of the registers to correct a flattening effect caused by higher aircolumn velocity. Also, the tonic note of the second register is usually played with the top hole of the whistle partially uncovered instead of covering all holes as with the
