Dreamaurora:bgmum:Hi Dreamaurora, thanks for the clarification. Think that's probably what he did
Yup.
To attempt the sight-singing well at the higher grades do need consistent singing practice to develop the vocal cord and to familiarize the more complex intervals.
So basically, a student who lacks opportunity to sing outside of piano lessons are severely disadvantaged when it comes to the sight-singing component of the aural. A teacher who is faced with such student will make a calculated decision whether to improve or to just forgo the sight-singing component if an exam is looming. Sight-singing takes time to improve and cannot simply be fixed within months for most students. It is only 1/3 of the aural test, so technically, if the section A and C of the Aural test is executed well, it is still merit overall as the penalty will be at most 3-4 marks.
This is why recently I incorporate singing homework for my lower grades now to slowly make them more comfortable to sing. A lot of local students I teach are very shy when it comes to singing because they are very self-conscious. So I am also thinking of incorporating vocal ensembles in the future.
not sure if this will help but hopefully it does. it helped me in my aural studies.
