In one section of the Trinity exam, the examiner will ask you 5 questions about your pieces. We are working through each piece to make sure we know all the symbols, key signatures, tempo markings etc. Here are some examples of worksheets I have been doing with one of my students for each of the Trinity Initial pieces. Do the same for your piece and see if you can answer all the questions.
You will also be expected to give the letter name of any note in the piece, plus know the key signature and names of clefs. Additionally, they will ask how the title of the piece relates to the music so do discuss this with your teacher.
Additionally do ensure you are practising the online aural tests at least twice a week in the run-up to the exam.

Aural Tests
Musical Knowledge (see below)
The examiner will ask candidates five questions in the exam, which test their understanding of the pieces played, their knowledge of the notation and their instrument. The examiner will first ask candidates to choose their favourite piece from the ones performed in the exam and will then ask some of the questions on that piece. The examiner will then choose one of the other pieces performed to complete the questions. The printed score should be free of annotations except for essential markings such as fingerings, breath marks etc. as appropriate. The examiner will usually point to part of the score when asking the questions
