It is difficult to hear but I would assume there is a golpe with the beginning of each position.
HERE is a slight variation of the preceding pulgar falseta.
Here are two chord movement focused falsetas. The first of them following a circle of fourths (the parenthesized notes with an asterisks above are the variant played in the second video below).
The second falseta strongly outlines the Andalusian cadence (iv III II I). It is difficult to discern the Bb chord variant (perhaps even an open G minor) in “Viejo Mundo” so I noted it as seen in Tomatito’s Rito y Geografía performance. The second falseta’s ending rhythmic flurry is different in both sources. In the second video, there is another falseta inserted between the two transcribed here.
