Note:
LC class numbers in subject authority records for choruses with accompaniment of piano (4 hands) indicate that "piano (4 hands)" is considered to be 1 keyboard instrument.
LC class numbers for in subject authority records for choruses with accompaniment of pianos (2) also fall within this range (M1548-1570 and M2061-M2080).
However, in some LC bibliographic records, choruses with accompaniment of 2 pianos are sometimes classed in M1543.5

Cutter numbers for special texts (for a complete list of texts, see Table M6)
If more than one language is present and one of those is Latin, use "L" in the cutter number.
  __11 Agnus Dei
  __14 Alma Redemptoris Mater
  __16 Ave Maria
  __161 Ave Maria Stella
  __165 Ave Verum corpus
  __169 Beatus vir
  __25 Cantate Domino

  __373 Dixit Dominus
  __4 Gloria in excelsis Deo
  __5 Kyrie eleison
  __6 Magnificat

  __7 Nunc dimittis
  __77 Regina Caeli
  __8 Salve Regina
  __82 Stabat Mater
  __9 Te Deum
  __94 Veni Creator Spiritus
For special texts not listed in Table M6, class works by medium of performance.

The M schedule doesn't offer a solution to special texts in languages other than those listed in the Table M6, but begin with the letter of one the languages listed there (e.g., "L" is used for Latin, and cannot be used with Latvian, Lithuanian, etc., special texts). The cuttering directions use up all the available numbers under a given letter, so unless a different lettering system were introduced for letters already occupied, there's no class legitimately available.
Several workarounds are possible:
1. Add a cutter number between "L" and the number for the text (e.g., La, Li),
2. Class with medium of performance instead of special texts,
3. Interfile all languages beginning with a specific alpha character without regard for their differences
