RE: double-dotted 8th notes

Sean,

You got it right the first time...I've had to explain this several times to
beginning drummers on my web site.

The way I explain it is to consider breaking down an eighth note into 2
sixteenth notes.  Add another sixteenth note to an eighth note and you've
got yourself a dotted-eighth note.

[shameless plug following...]

See my Dotted Eighth Note drum lesson:
http://216.103.111.115/perl/drums/index.cgi?Action=OnlineLessons&Skill=Advan
ced&SubCategory=Dotted%20Eighth%20Notes&LessonID=Advanced2

BTW, all the MIDI files on my web site were created using MIDI Perl - whoo
hoo!!

Thanks Sean for all your hard work on this wonderful perl module.

Regards,
Scott

Subject: double-dotted 8th notes


I was just looking at MIDI/Simple.pm's %Length hash:

  'wn' =>  4,     'dwn' => 6,    'ddwn' => 7,       'twn' => (8/3),
  'hn' =>  2,     'dhn' => 3,    'ddhn' => 3.5,     'thn' => (4/3),
  'qn' =>  1,     'dqn' => 1.5,  'ddqn' => 1.75,    'tqn' => (2/3),
  'en' => .5,     'den' => .75,  'dden' => .75,     'ten' => (1/3),
  'sn' => .25,    'dsn' => .375, 'ddsn' => .4375,   'tsn' => (1/6),

and I've looked at this a million times before, but today I just happened
to notice: that says an 8th note is half a quarter note, and a dotted-8th
is .75 of a quarter note, AS IS a double-dotted 8th note?!  That can't be
right, can it?
Shouldn't a double-dotted 8th note be... um... 7/8ths of a quarter
note?  7/16ths?  Aaaaaaaa Rickeeeee music theory hurts my head waaaaaaa...
