Cantata BWV 8, entitled Liebster Gott, wenn werd ich sterben? ("Beloved God, when shall I die?"), is a choral cantata (Choralkantate) belonging to the cycle of choral cantatas from Bach's second year as Thomaskantor in Leipzig (1724-1725). It was premiered on September 24, 1724, at St. Nicholas Church (St. Nikolaikirche) in Leipzig. Bach composed it for the sixteenth Sunday after Trinity. The readings for the day included Luke 7:11-17 (the resurrection of the young man of Nain), which is thematically related to the reflection on death, resurrection, and trust in God.
The work is based on the Lutheran hymn Liebster Gott, wann werd ich sterben by Caspar Neumann, written around 1690 (five stanzas). The melody was composed by Daniel Vetter in the early 1690s and first published in 1713. Bach used the text of the hymn literally in the outer movements (stanza 1 in the opening chorus and the final stanza in the concluding chorale). An unknown librettist paraphrased the middle stanzas for the recitatives and arias, focusing on meditation on death, the passage of time, and faith in divine salvation.
The cantata consists of six movements:
- Chorus – Liebster Gott, wenn werd ich sterben? (stanza 1 of the hymn, extensive choral fantasy with cantus firmus in the soprano, accompanied by repetitive motifs evoking the ticking of a clock or the passage of time).
- Aria (tenor) – With oboe d'amore obbligato.
- Recitative (alto).
- Aria (soprano) – With obbligato transverse flute and pizzicato strings.
- Recitative (bass).
- Choral – Final verse of the hymn, harmonized for four voices.
The opening chorus is particularly famous for its symbolic sound (repetitive "tick-tock" on the flute and continuo, representing the fleeting nature of life).
Instrumentation
- Transverse flute (or piccolo in some sources).
- Two oboes d'amore.
- Horn or taille (doubling the cantus firmus in the opening chorus).
- 2 violins.
- Viola.
- Basso continuo.
- Four-part choir (SATB).
- Soloists: soprano, alto, tenor, and bass.
The instrumentation is notable for the obbligati of flute and oboe d'amore, which lend a pastoral and contemplative tone, reinforcing the theme of peaceful death and trust in God.
