(2) Which incidentally means that for him Andante was not a slow tempo!

(5) He only used 3/2 and 4/2 – and characteristically without a tempo indication – in several movements in the stilo antico: in K. 49, 85 and 321, and never 6/4; these meters were by that time already considered as old-fashioned.
(6) In some 190 cases even foreword and critical notes give no information on the source.
(7) If René Leibowitz insists that Mozart’s Andante ¢ should be conducted in half notes, to be consistent he would then also have to conduct the Presto-3/8 sections in eighth notes, which of course he does not. ("Tempo und dramatischer Sinn in Mozart’s ‚Don Giovanni", in: "Mozart. Die Da Ponte-Opern", "Musik-Konzepte", Sonderband, ed. text + kritik, München, 1991, 212fn)
(8) 508 out of 725 movements by Mozart in 4/4 time belong to this category.

(10) Hans Swarowsky / Manfred Huss, "Wahrung der Gestalt", Wien, 1979, p 76: "The establishment of the modern way of conducting has robbed much of the feeling for a naturally appropriate tempo". And also very nice: "Music which has never asked to be conducted is the most difficult music to conduct."
(11) There is also the modern term "added" meter, which to my mind does not make it clear enough that measures as entitiesare meant.
(12) With regard to 6/8 meter this should read four "weak" beats; Koch had taken the wording uncorrected from the entry on 4/4 meter. (Heinrich Christoph Koch "Musikalisches Lexikon", Frankfurt, 1802, reprint: Hildesheim, Georg Olms, 1964, c. 1307 and 1482.

("Bemerkungen über die Ausbildung der Tonkunst in Deutschland im achtzehnten Jahrhundert") ["Remarks on the cultivation of the art of music in Germany in the eighteenth century"].

Among other things they refer to the numerous new time signatures – nonsensical as proportions –, to corresponding statements in certain treatises [...] and forewords as well as the complete absence of any references to a proportional interpretation e.g. of the verbal tempo indications."

Tempo, dynamics, articulation, agogics and embellishments are the essential components of a good "Vortrag"." [This is the gist of what F.W. Marpurg says about "Vortrag" in his "Critical Letters about the Art of Music" (1760) vol. I, p 500]. - H.Chr.

(31) And I dare to consider that Beethoven’s – and our own – difficulties with his metronomization stem from this.
(32) Jean-Pierre Marty ("The Tempo Indications of Mozart", 1988), bases his somewhat subjective metronomization of Mozart’s tempi on an arbitrary scale of walking speeds of either MM=60 or MM=44, which in a classical circular reasoning leads to such statements as all of Mozart’s Andante ¢ were either 1/2=60 or 1/2=44.
