Move A Picture With Timer?

I create my fisrt game for a school project, it's a music game very simple and fun. We have a picture of a guitar, a song that play in background and we need to shoot some picture of note in the right time.My problem is that I don't understand how to move the picturebox by itself. I have doing this code and that don't work.

Dim intX As Integer
Dim intLargeurFeuille As Integer = Me.Width
Dim intLargeurImage As Integer = picNote.Width

[code]...

I want to make move a sequence of note, i have begin for just one but that not great. I want to, when in a specific moment of the song that paying, to make move a group of note. Also, the group of note need to move to a place in a specific time.

So what I need is

- Move note to a place in a specific time
- Begin the movement of the note at a specific time.
- The note move only on the X, to right to left
