Detailed accounts of the coronations of the two Brazilian emperors exist, such as a very meticulous account of the coronation of emperor Dom Pedro II published by Rio de Janeiro's Jornal do Commercio newspaper on 20 July 1840 The said account, in full, is also published in the book by Lima, J. I. de Abreu. Compêndio da História do Brasil, volume 2, pp. 176 et seq, available at https://books.google.com/books?id=VdhWAAAAcAAJ&pg=RA2-PA180 and in the works of historiansShubert, Guilherme. A coroação de D. Pedro I, Rio de Janeiro, Arquivo Nacional, 1973Sousa, Octavio Tarquinio de. Historia dos Fundadores do Império do Brasil, vol. II, p. 448 et seq. Another source describing the proceedings that were to be observed in the coronation of emperor Dom Pedro I, including the ceremony for the taking of civil oaths (not prescribed in the Roman Pontifical) that were to be sworn at the conclusion of the liturgy, is the document Ceremonial of the consecration and coronation of Emperor Pedro I that is to take place in the Imperial Chapel of Our Lady of Mount Carmel on the 1st day of December of the current year, that was approved by the imperial government on 20 November 1822 and is contained in a letter addressed by the Minister for the Empire, José Bonifácio de Andrada e Silva, to the imperial court's officers of arms. The said ceremonial was published in the volume of Government Decisions of the Collection of the Laws of Brazil for the year 1822. All those ceremonials and accounts of the festivities are only lacking on the question of the music that was played during the coronation liturgy (e.g. for the entrance and departure processions, etc.)
