the First series with Red: giving to the e, and all of the Second 
series, the Yellow, which, to show well by artificial light will 
e well done by gold. In like manner, the Third series, that 
of the Sevenths, indicated pie a gothic ugha will be colored 
Blue.* Nothing remains but to call the tones by distinctive 
names. The syllables of Guido answered 1 this purpose when 
there was no “modulation within the key,” and no account 
made of Perfect sevenths. T'o the modern syllables re two, 
which were not in the original i in the “Ut queant laxis ;” to wit, 
the “Do,” and the “Si.” Keeping the Do as it is, and changing 
the initial Tether of the si, so as not to confuse it hereafter with 
that of sol, we may find a common ending to all the notes of the 
first series, or that of the Fifths. These are the Ist, 2d, 4th and 
5th. Preserving the lst and 5th as they are, but rejecting be 
final letter of the sol, and making the rest conform, we shall h 
Do, Ro, Fo and So. Their class is known by the abiding ; 
the place of each in the scale by the initial consonant. For the 
second class, that of the Thirds, mi, la, si, we preserve also the 
present termination of the majority, and have mi, li, and Zi. 
-For the Perfect sevenths or Third series, which are generally 
sounded by the termination of e (Italian), we preserve the same, 
and zi flat is Ze. And the dominant seventh, lower than Fa, 
will be Fe. There are two different Diatonic Scales oreuel 
as the Seventh 4:7, is introduced or not; they will be ex 
in reference to their syllables for singing, their letters. Fol,
