Chord Transpose

Statement

 Goal

Your friend Alice wants to play the piano but finds it difficult to learn chords. So you decided to write a tool that will help her to practice.

Your script should take a notes series notes and transpose it by semitones. It means moving all the notes up (or down for negative semitones) the same number of semitones (keys). A keyboard consists of notes:
C C# D D# E F F# G G# A A# B
and they are cycled, so after a 'B' it's a 'C' again and so on.
Input
Line 1 : A string notes with notes separated by spaces.
Line 2 : An integer semitones showing the number of keys to move.
Output
A single line containing a transposed notes series. Notes are separated by spaces.
Constraints
notes can have from 1 to 3 notes.
-48 <= semitones <= 48
