REVIEW OF THE NEW MUSICAL PUBLICATIONS. 

NUMBER VIII. of Guida Harmonica; o> 
and the mufical proportions. The frft 
an Introduftion to the general Knowledge of part is divided inio nine chapters: the 
Mufic theoretical and pra€tical, in two Parts. 
The firft Part, confifting of Sonatas, Airs, &c. 
for the Piano-forte; the fecond containing Ef- 
fayson the feveral Branches of the Science, with 
‘Tiluftrations, Rules, Gc. by J. Roilfe. 
4s. 6d. Broderip, Wilkinfou, and Skillern. 
The prefent number of a work, which 
we have long fince introduced to the no- 
tice of our miufical readers, commences 
with an excellent fonata (the feventh in 
this publication), after which the author 
enters upon an efiay on accompaniment. 
Some ufeful remarks on the fen/fble note, 
the difcord of the flat fewenth, and the 
treatment of the dominant harmony, have 
particularly caught our eye, and impreffed 
us with the confidence, that the author is 
not only adequate to the great tafk he has 
impofed on himfelf in this undertaking, 
but is no lefs diligent and zealous in this 
late ftage of its progrefs, than he evinced 
him(elf to be in the earlier parts of his 
labours. After the eflay on accompani- 
ment, which is divided into two parts, 
we find an eflay on the method of analyfing 
a compolition, with fuitable illu@rations 
and examples, in which the mufical ftu-> 
dent will find much valuable information 
on the fubject of compofition, as well as 
in the fucceeding eflay on irregular har- 
monies, which conclude the prefent elabo- 
rate and ingenious number of Guida Har- 
Monica. . 
Lhe firft Part of the Book of Precepts of a complete 
Treatife on Mujfic, by Mr. Bemetzrieder. 5s. 
Longman, Clementi, and Co. 
This dida&ic work.is to be comprifed 
in three numbers, or parts, making in the 
whole a fifteen fhilling book, in quarto. 
The fir? part contains the principles and 
method ¢* which make eafy the reading of 
mufic, playing, folaing, and finging ;” 
the /econd part is to treat of thorough ba/s, 
accompaniment, the prelude, and the art of 
playing and finging; and the third part is 
to explain the principles of iran/po/tion, 
I 
. 
fit chapter lays down the firft elements, 
as far as concern the notes and clefs. The 
Jecond prefents a fhort and eafy method of 
learning the folfa uponall the clefs; the third 
gives the form, value, and movement of 
the mufical notes, and marks of filence ; the 
Jourth treats of time ; the fifih contains ligns 
for altering and embellifhing notes ; the /e- 
wventh comprifes the various mufical cha- 
racters, and recapitulates the feveral Ita- 
lian words ufed to direét the ftyle of per- 
formance ; the ezehih {peaks of the extent 
of an air or tune; and the ziath applies 
the previous rudiments to praétice. On 
caretully furveying the whole work, we 
find the feveral_parts judicioufly laid out, 
and the plan well-digefted, and cannot but 
be of opinion that it will be found very 
ufeful to young mufical ftudents, and tend 
to fave much time and trouble both to the 
matter and pupil. 
Tiree Duetts for two Violins; exprefly coms 
poled for the Uje of Teachers, and the Im- 
provement of juvenile Performers, in which is 
introduced the celebrated Air of the Cottage om

Riley. 
The ingenious author of thefe duetts 
has adopted a mode of inftru€tion perfe&t- 
ly novel we believe in violin exerciles ; 
but not more zew than weful. The lead- 
ing notes of every paflage of importance 
are fingered as in piano-forte mufic, and 
the practitioner confequently guarded. a- 
gaint that awkward and unmatterly ftyle 
of fingering to which, without fuch a 
guide, he is continually liable, notwith- 
fianding the meft wary attention of his 
tutor, Mr. Sanderfon, whe, in the pre- 
fent compofitions, has acquitted himfelf 
with confiderable tatte and judgment, 
gives in his title-page his reafons for 
adopting this ufeful plan, which reafons , 
we quote in his own language for the be- 
nefit of the attentive pupil.
