Updated Day Five - today we are adding the dotted crotchet and the tie. A tie is where two notes are 'tied' together, you don't play a new note, just keep the bow moving the same way. In line one we have a bar of half count notes, bar two has a one crotchet and two quavers. Bar three 'ties together the crotchet and the quaver. Bar four uses a dotted crotchet - this is exactly the same as tieing together the crotchet and the quaver. So bars 3 and 4 sound exactly the same.
