EOLL, in dramming, is a tremolo -effect on
the side-drum, produced by a certain varied
method of playing according to the kind of roll
desired. The first practice of this is called
'
daddy mammy,' which, commencing deliberately,
with a long stroke for each syllable,
gradually increases in speed until the beats are
merged into one continuous roll. The 'long
roll ' is an alternate beat of two with the left
stick, followed by two with the right. The
'
five stroke roll ' is two with the left, two
with the right, one with the left, two with the
right, two with the left, and one with the

right ; or more briefly
The ' seven stroke roll ' is—L L R n L L . K. The
'
nine stroke roll ' is—L lerllrr.l followed
by a short rest, and krllrrll..r. EoUs
on the timpani are made by the simple altemanation
of strokes with the two sticks. See

EOLLA, Albssandro, violinist and composer,

studied the pianoforte, but soon exchanged it
for the violin, which he learned under Eenzi
and Conti. He had also a great predilection
for the viola, and wrote and performed in
public concertos for that instrument. In
1782-1802 he was leader of the band at Parma,
and it was there that Paganini was for some
months his pupil. [See Pabanini.] In 1802
he went to Milan as leader and conductor of
the opera at La Scala, in which position he
gained a great reputation. He became in
1805 a professor at the Conservatorio of Milan,
and died in that town, Sept. 15, 1841, aged
eighty -four. Hia compositions, now entirely
forgotten, had considerable success in their
time ; they consist of a large number of violin
duets, some serenades, trios, quartets, and
quintets for stringed instruments, and concertos
for the violin and for the viola, as well
as songs. (See the Quellen-Lexilcon. ) His son
and pupil, Antonio, violinist, was bora at

Christian Carl, bom at QuedUnburg in 1714,
was Cantor of the Jerusalem Church, Berlin,
about 1760, but was apparently of no account.
He had sons, of whom Friedrich Hein-
KICH left a biography of his father ; while
Christian Carl (the younger) succeeded him
as Cantor. 2. A second son is mentioned, but
without Aame. 3. The third, JoHANN Hein-
RICH, was bom at Quedlinburg, Dec. 23, 1718,
and at an early age began to play and to write.
He held the post of organist at St. Peter's,
Magdeburg, in 1732 when only fourteen years
old (^Quellen-Lexikon). He was at the Leipzig
University in 1736, and migrated to Berlin in
hopes of some legal post ; but this failing he
adopted music as his career, and about 1740
entered the Court chapel of Frederick the Great
as a chamber musician (viola player). There
he remained till 1746, and then took the
organist's place at the Johanniskirche, Magdeburg,
as town musician, worked there with
uncommon zeal and efficiency, and died at the
age of sixty-seven. Dee. 29, 1785. His industry
seems almost to have rivalled that of Bach himself.
He left several complete annual series of
church music for all the Sundays and Festivals ;
cantatas for Easter, Whitsuntide, and Christmas,
