One that seems to be missing is a tenor voice clef symbol that is the G clef in its normal position but with a small 8 attached to the bottom of the symbol. I've only seen it used in choral music for Tenor voice.
Yes, that is equivalent to the male-voice F clef I mentioned. There's also the G ("treble") clef with an 8 attached to the
top of the symbol—sounding an octave higher. Used for soprano, sopranino, and higher-sounding recorders, &c.
For the garklein (a recorder sounding two octaves above the written notes of a standard G clef), the notation 15 above the symbol is sometimes used. Why “15” instead of “16”? I’ll let the Google AI agent answer that in typical clear and well-presented style.
AI Overview
To play notes two octaves higher on the treble clef, you would use the notation 15ma, which stands for
quindicesima (Italian for fifteenth), not 16ma.
Here's the reasoning behind using "15" instead of "16":
1. Interval Counting: In traditional Western music theory, intervals are typically counted inclusively, meaning both the starting and ending notes are counted as part of the interval.
2. Octaves as a reference: An octave spans eight notes when counting inclusively (for example, C to the next C).
3. Calculating two octaves: If you consider the interval of two octaves, you're essentially going up 7 scale steps, then another 7 scale steps, which totals 14 scale steps. However, when counting the interval inclusively, you count the starting note as "1," then count up 14 more notes to reach the note two octaves higher. This results in a total of 15 notes, making it a "fifteenth". For example, if you start on C (1), going up two octaves leads you to the next C (8), and then another C (15).
4. Established Terminology: The term quindicesima (fifteenth) for a double octave is ingrained in musical tradition and established terminology.
In essence, the choice of 15ma rather than 16ma reflects the traditional way of counting musical intervals in a diatonic scale, where both the starting and ending notes are included in the count, rather than a direct mathematical multiplication of 8 by 2 to get 16.
