meaning of 1=(note) and (note)b and b(note) and #(note) in jianpu?

[natsuhinaa]

so i saw a jianpu and they have keys like 

1=(note)
(note)b
b(note)
#(note)

and also bpm = (numbers)

what does they mean?

for example 

1=D
5b
b6
#3

BPM = 66

Well, 1=D means that the key of the tune is in D. When you see a '1' in the jianpu score, it indicates the note 'D'. BPM = 66 is probably a metronome setting - Beats per Minute).

Usually in a jianpu score for erhu, after the key signature (1=D), there will be a set of numbers in parentheses indicating the scale degrees of the open strings. So, for the key of D you will see 1=D (1 5). The A string (outside) is 5, or the fifth scale degree in the key of D. I don't know what 5b b6 #3 means. Maybe we could figure out the meaning if you posted an image of the score.

Best wishes,

David

Hi,

My guess is # and b means sharp and flat.
