Johann Friedrich Alberti (11 January 1642 – 14 June 1710) was a German composer and organist.
Alberti was born in Tönning, Schleswig and died, aged 68, in Merseburg, Saxony-Anhalt.
He received his musical training in Leipzig from Werner Fabricius and in Dresden from Vincenzo Albrici. Then he worked as an organist in Merseburg cathedral until his departure in 1698 caused by the paralysis of his right hand because of a stroke. His pupil was Georg Friedrich Kauffmann.
Alberti's works include chorale preludes, 35 choral arrangements, 12 ricercati (lost) and various sacred works.
Just in case you wonder, Alberti bass is a particular kind of accompaniment figure in music and named after Domenico Alberti (1710–1740/46), who used it extensively, although he was not the first to use it.
The two works are;
Gelobet seist du
Herzlich lieb hab ich dich, o Herr
