First of all I want to say that you have selected an excellent version of the Missal! The instructions are to lengthy to put into threads. But the above response is a start. You must learn how to go from the Ordinary of the Mass to the Proper and back again to the Ordinary and so forth. You would normally start the Mass in the Ordinary with theSign of the Cross followed by thePrayers at the Foot of the Altar(I will go to the Altar of God…). Sometimes this is recognizable with red print interladen in the text.Then after the Gloria, you would go to the Proper of the Day, like xx Sunday after Pentacost. There you would find the Collect and readings and other necessary prayers for the Mass. After the readings you would return to the Ordinary for the Creed. By now you will be in the flow of things and maybe can follow. The most important part of the Mass, the Canon, is in the ordinary. It is hard to follow the Priest in all these things. He may be faster than you are!! Then you will panic and lose conscentration on the Mass. My recommendation is to participate in the prayers at the foot of the altar, the Confiteor, the Gloria, the Collect, the Creed, the Our Father, Agnus Dei, the final Blessing, and the Last Gospel. Whew!! It will come with time. An excellent book for attending the Tridentine Mass is by St. Leonard. OOps, I forgot the title. It is published by Tan Books, and title has Mass in it. By the way the Canon of the Tridentine Mass is almost equivalent to the Eucharistic Prayer I of the New Mass. The Canon is said in silence and is the Work of the Priest. We cannot do what he can do and that is transubstantiation. We pray at this moment on Calvary and listen to the bell that brings for Christ’s Death, The separation of the Body and Blood of our Lord. Later in the Mass a Piece of the Sacred Host is put into the Chalice to represent His Ressurrection! I hope this helps some! There is alot to learn, but with alittle perseverance it will begin to come together.
