Jean-Siegfried Blumann (1887–1965) was a German conductor and composer. He graduated from the Hamburg Conservatory's conducting class and continued his studies at the Vienna Conservatory. During his artistic career, he worked as a Kapellmeister at several German-language theatres, including in Schwerin, Lübeck, Magdeburg, Braunschweig, Breslau and at the Kroll Opera in Berlin. As a composer, Jean S. Blumann also wrote entertaining works in addition to concert pieces, études and plays. The present piece for trumpet and piano (alternatively organ) is an example of his light compositional style.

Throughout church history, the Te Deum and the Gloria , both of which are early Christian hymns, have been set to music many times. In this handwritten score, Siegfried Borris (1906-1987) has arranged the Te Deum for oboe and organ – alternatively, it can also be performed with trumpet (D) or piano.

Lotte Backes (1901–1990), recipient of the Federal Cross of Merit, was a German pianist, organist and composer. She studied composition at the Prussian Academy of Arts and lost much of her early work during the Second World War. The present work, episodio per tomba e organo , dates from her post-war period and is available as a facsimile edition.
