Septimal buzzard is not only a naturally motivated extension to 2.3.7 buzzard, but the main extension to [[vulture]] of practical interest, finding prime 7 at only 3 generators down so that the generator is interpreted as a sharp ~[[21/16]], though buzzard is powerful as a full 13-limit system in its own right. It is most naturally described as 53 & 58 (though [[48edo]] is an interesting higher-damage tuning of it for some purposes). As one might expect, [[111edo]] (111 = 53 + 58) is a great tuning for it.

Its 13-limit [[S-expression]]-based comma list is {[[1728/1715|S6/S7]], [[5120/5103|S8/S9]], [[847/845|S11/S13]], [[676/675|S13/S15]]}, with the structure of its 7-limit implied by the first two equivalences combined with the nontrivial [[JI]] equivalence [[36/35|S6]] = [[64/63|S8]] × [[81/80|S9]]. [[Hemifamity]] leverages it by splitting [[36/35]] into two syntonic~septimal commas, so buzzard naturally finds an interval between [[6/5]] and [[7/6]] which in the 7-limit is [[32/27]] and in the 13-limit is [[13/11]]. Then the vanishing of the orwellisma implies [[49/48]], the large septimal diesis, is equated with 36/35, so 49/48 is also split into two so that the system also finds an interval between 7/6 and 8/7 which in the 7-limit is 7/6 inflected down by a comma or 8/7 inflected up by a comma, and in the 13-limit is [[15/13]], so that it is clear this system naturally wants to be extended to and interpreted in the full 13-limit. | Its 13-limit [[S-expression]]-based comma list is {[[1728/1715|S6/S7]], [[5120/5103|S8/S9]], [[847/845|S11/S13]], [[676/675|S13/S15]]}, with the structure of its 7-limit implied by the first two equivalences combined with the nontrivial [[JI]] equivalence [[36/35|S6]] = [[64/63|S8]] × [[81/80|S9]].

- This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.
The 2.3.7-subgroup comma for the buzzardsmic clan is the buzzardsma, 65536/64827, with monzo [16 -3 0 -4⟩, which implies that the tritave, 3/1, is divided into four intervals each representing a 21/16 subfourth. Tempering out this comma implies a sharpened 7th harmonic, and especially a sharpened ~21/16 generator, which approaches the 480 ¢ fourth of 5edo.
Extensions of buzzard to incorporate prime 5 along its chain of generators (and therefore the full 7-limit) include septimal buzzard (53 & 58), which tempers out 1728/1715 (and 5120/5103); subfourth (58 & 63), which tempers out 10976/10935; and lemongrass (63 & 68), which tempers out 245/243. All are considered below.
Weak extensions include submajor (10 & 43), which tempers out 225/224 and splits 32/21 (the superfifth) in two; and thuja (15 & 43), which tempers out 126/125 and splits 21/8 into three.
Full 7-limit temperaments discussed elsewhere are:
- Blackwood (+28/27) → Limmic temperaments
- Quadrasruta (+2048/2025) → Diaschismic family
- Hemikleismic (+4000/3969) → Kleismic family
- Cohemimabila (+3136/3125) → Mabila family
The rest are considered below.

Strong extensions
Septimal buzzard
Septimal buzzard is not only a naturally motivated extension to 2.3.7 buzzard, but the main extension to vulture of practical interest, finding prime 7 at only 3 generators down so that the generator is interpreted as a sharp ~21/16, though buzzard is powerful as a full 13-limit system in its own right. It is most naturally described as 53 & 58 (though 48edo is an interesting higher-damage tuning of it for some purposes). As one might expect, 111edo (111 = 53 + 58) is a great tuning for it. Mos scales of 5, 8, 13, 18, 23, 28, 33, 38, 43, 48 or 53 notes are available.
Its 13-limit S-expression-based comma list is {S6/S7, S8/S9, S11/S13, S13/S15}, with the structure of its 7-limit implied by the first two equivalences combined with the nontrivial JI equivalence S6 = S8 × S9. Hemifamity leverages it by splitting 36/35 into two syntonic~septimal commas, so buzzard naturally finds an interval between 6/5 and 7/6 which in the 7-limit is 32/27 and in the 13-limit is 13/11. Then the vanishing of the orwellisma implies 49/48, the large septimal diesis, is equated with 36/35, so 49/48 is also split into two so that the system also finds an interval between 7/6 and 8/7 which in the 7-limit is 7/6 inflected down by a comma or 8/7 inflected up by a comma, and in the 13-limit is 15/13, so that it is clear this system naturally wants to be extended to and interpreted in the full 13-limit.

2.3.5.7.13 subgroup
This temperament naturally comes about from a structure in edos like 43 and 53 where two flattened ~13/8 intervals reach the buzzard generator of ~21/16, two of which produce a semitritave (that can here be equated to 26/15, providing a mapping of 5 significantly less complex than the vulture mapping), and two of those finally reach 3/1.
