I have Volume V of the Soneto edition, Mark, and La Alborada ("o amanhecer" in Portuguese, meaning sun rising, dawn) is the first piece in it (SEM 23, pages 14-15). The title of the piece is LA ALBORADA and, underneath it (Juguete dedicado a mi hijito Paco). In what concerns your question, Mr. Melchor Rodríguez always includes at the beginning of its Volumes photocopies of one or two original handwritten manuscripts (not necessarily complete) of scores of pieces in the Volume. In this case, the complete handwritten score of La Alborada is the one presented, in page 13. The title is LA Alborada "Juguete dedicado a mi Hijito Paco - Tárrega (ipsis verbis, no closing of the quotation mark). There follows the complete score occupying five staffs (the empty page had 10 staffs, the first was used for the tittle and the 2nd, 4th, 6th, 8th and 10th for the musical notes, ending with Valencia 21-Junio 91- followed by his signature "Franc_ Tárrega".
In his English translated notes concerning this piece (in page 99), Mr. Rodríguez writes (ipsis verbis):
LA ALBORADA - SEM No. 23, page 14 (Musical toy Dedicated to my little son, Paco)
The Lied form of this short, amusing piece suggests the sound of a musical toy, as its dedication indicates, especially in Section B, in which the crystalline sound of its artificial harmonics is made even more patent.
