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.
