  Music Information Retrieval (MIR) technologies have been proven useful in
assisting western classical singing training. Jingju (also known as Beijing or
Peking opera) singing is different from western singing in terms of most of the
perceptual dimensions, and the trainees are taught by using mouth/heart method.
In this paper, we first present the training method used in the professional
jingju training classroom scenario and show the potential benefits of
introducing the MIR technologies into the training process. The main part of
this paper dedicates to identify the potential MIR technologies for jingju
singing training. To this intent, we answer the question: how the jingju
singing tutors and trainees value the importance of each jingju musical
dimension-intonation, rhythm, loudness, tone quality and pronunciation? This is
done by (i) classifying the classroom singing practices, tutor's verbal
feedbacks into these 5 dimensions, (ii) surveying the trainees. Then, with the
help of the music signal analysis, a finer inspection on the classroom practice
recording examples reveals the detailed elements in the training process.
Finally, based on the above analysis, several potential MIR technologies are
identified and would be useful for the jingju singing training.
