In recent years it has become more common for bishops to celebrate Sung Mass more sacerdotali, that is, just as priests do and without the sacred ministers (subdeacon, deacon and assistant priest) and ceremonies peculiar to a Solemn Pontifical Mass. This has to do with the difficulty in most places of having enough sacred ministers, and the desire to have something like a Solemn Pontifical Mass whenever there is a bishop available to celebrate Mass according to the 1962 Missal. Unfortunately, the "Pontifical Sung Mass" was not foreseen in the rubrics of the liturgical books in force by the end of 1962, raising endless questions about the licitness of the practice. In response to a dubium from a Traditional Catholic choir in the Philippines, the PCED has now responded with a clarification on Pontifical Sung Masses.
In summary: bishops who wish to celebrate according to the 1962 Missal are to choose between Low and Solemn Pontifical Mass. The "Pontifical Sung Mass" is not among the choices.
