Christmas (bleeper) tunes

I’ve encoded some Christmas carols for an arduino driven buzzer (so I can annoy my colleagues) and thought I’d share.

Notes: note ‘s’ is a f#, v is a b-flat.

Code is as here:
Replace the definition of the notes with these two lines (you need more notes than are defined in the example):

char names[] = { 'c', 'd', 'e', 'f', 's', 'g', 'a', 'v', 'b', 'C', 'D', 'E' };
int tones[] = { 1915, 1700, 1519, 1432, 1352, 1275, 1136, 1073, 1014, 956, 852, 758 };

I also changed the tempo to 150.

Replace length, notes and beats with any of the following…

Ding Dong Merrily on High

int length = 73;
char notes[] = "ggagsed deggsgg ggagsed deggsgg DCbCDbCbabCabagabgagsgasgsesgeseddeggsgg "; // a space represents a rest
int beats[] = { 2,2,1,1,1,1,4,2,2,2,2,2,2,4,2,2,2,2,1,1,1,1,4,2,2,2,2,2,2,4,2,2,3,1,1,1,1,1,3,1,1,1,1,1,3,1,1,1,1,1,3,1,1,1,1,1,3,1,1,1,1,1,3,1,2,2,2,2,2,2,4,2,2 };

God Rest Ye Merry Gentlemen

int length = 69;
char notes[] = "ddaagfedcdefga ddaagfedcdefga avgavCDagfdefgfgavaagfedfedgfgavCDagfed";
int beats[] = { 2,2,2,2,2,2,2,2,2,2,2,2,2,4,2,2,2,2,2,2,2,2,2,2,2,2,2,2,4,2,2,2,2,2,2,2,2,2,2,2,2,2,2,4,2,2,4,2,2,2,2,2,2,4,1,1,2,4,2,2,2,2,2,2,2,2,2,2,8 };

While Shephards Watched

int length = 29;
char notes[] = "faagfvvagaCCbCaDCvagfeagffef ";
int beats[] = { 2,3,1,2,2,2,2,2,2,2,2,2,2,6,2,3,1,2,2,2,2,2,2,2,2,2,2,6,2 };

In The Bleak Midwinter

int length = 51;
char notes[] = "aavCagfgagdgavCaggfgagff vavCDDaaCagfecavCagfgagff ";
int beats[] = { 2,3,1,2,2,4,4,3,1,2,2,8,3,1,2,2,3,1,4,2,2,3,1,6,2,3,1,2,2,2,2,2,2,2,2,2,2,6,2,2,2,2,2,4,4,2,2,3,1,8,8};

can I ask you how does someone can take a music and make a perfect fit to the arduino without being a music player/audio type guy?
Ive been looking for that answer from a long time now :-/


Nice! Going to try this when I get home! :smiley:

Depends what you mean by ‘music’. The buzzer above is pretty simple, it uses code from an example. I did need a bit of music knowledge to convert the songs though.

If you want ‘proper’ music you could look at an mp3 shield which will allow you to trigger mp3s being played from your adruino.

I like the third one the best.

I found some more Christmas songs that work with the RTTTL example in the Tone library:
for example, "We wish you a merry Christmas:

char *song = "WeWishYou:d=4,o=5,b=200:d,g,8g,8a,8g,8f#,e,e,e,a,8a,8b,8a,8g,f#,d,d,b,8b,8c6,8b,8a,g,e,d,e,a,f#,2g,d,g,8g,8a,8g,8f#,e,e,e,a,8a,8b,8a,8g,f#,d,d,b,8b,8c6,8b,8a,g,e,d,e,a,f#,1g,d,g,g,g,2f#,f#,g,f#,e,2d,a,b,8a,8a,8g,8g,d6,d,d,e,a,f#,2g";
