shoshanim / shushan (lilies / lily; Pss. 45; 60), said to be describing a certain melody; or ʻalmuth / ʻalamoth (mute; Pss. 9, 46), which, according to Saadia Gaon, is "a silent melody, nearly inaudible." Despite the frequently heard view that their ancient music is lost, the means to reconstruct it are still extant. Fragments of temple psalmody are preserved in ancient synagogue and church chant, particularly in the tonus peregrinus melody to Psalm 114. Cantillation signs, to record the melody sung, were in use since ancient times; evidence of them can be found in the manuscripts of the oldest extant copies of Psalms in the Dead Sea Scrolls and are even more extensive in the Masoretic text, which dates to the Early Middle Ages and whose Tiberian scribes claimed to be basing their work on temple-period signs. (See Moshe ben Asher's 'Song of the Vine' colophon to the Codex Cairensis). Several attempts have been made to decode the Masoretic cantillation, but the most "successful" is that of Suzanne Haïk-Vantoura (1928–2000) in the last quarter of the 20th century. Her reconstruction assumes the signs represent the degrees of various musical scales – that is, individual notes – which puts it at odds with all other existing traditions, where the signs invariably represent melodic motifs; it also takes no account of the existence of older systems of notation, such as the Babylonian and Palestinian systems. Musicologists have therefore rejected Haïk-Vantoura's theories, with her results dubious, and her methodology flawed. In spite of this, Mitchell has repeatedly defended it, showing that, when applied to the Masoretic cantillation of Psalm 114, it produces a melody recognizable as the tonus peregrinus of church and synagogue. Mitchell includes musical transcriptions of the temple psalmody of Psalms 120–134 in his commentary on the Songs of Ascents. Regardless of academic research, Sephardic Jews have retained a tradition in the Masoretic cantillation. Themes and execution Most individual psalms involve the praise of God for his power and beneficence, for his creation of the world, and for his past acts of deliverance for Israel. They envision a world in which everyone and everything will praise God, and God in turn will hear their prayers and respond. Sometimes God "hides his face" and refuses to respond, questioning (for the psalmist) the relationship between God and prayer which is the underlying assumption of the Book of Psalms. Some psalms are called
