I need the names of the following symbols:
- The one that is not coloured in and looks like a "d"
- The circular one, that looks like an "o"
- The one like this ♪, but doesn't have the little thingy sticking out
The ♪ symbol is called a quaver, it represents 1/8th of the total duration represented by a full note
The one that looks similar to ♪, but doesn't have the little thingy sticking out and is not coloured inside is called a minim and is half of a full note
PS: if I understand it correctly, the "common name" above refers to what they are known as in the US. The traditional names for the notes are the ones in the Classical Note Name and are also more frequently used in music books
EDIT My answer has the most upvotes (as I type this). However I now believe that the answer provided by user13267 is better. I also think that the answer by Drew adds useful information.
In the US, the answer is as given by the user lightbulb.
In the UK we have individual names for them. ♪ is a quaver, ♩ is a crotchet. Then we have minim, semibreve and breve.

♩ is named

This, empty-"d" character,
𝅗𝅥, is named
