I use soundslice a lot as a learning tool in my lessons. Soundslice is a website where music teachers can post content that enables students to play along with a video. As the music progresses in time, the sheet music moves as well, making it very clear for the student what they have to play. It is very easy to slow the music down or to select a loop of a difficult passage, for a better learning experience. 

I post different kinds of content on my soundslice page. Content on soundslice is called a 'slice'. 
-Play along chord slices. With the audio (usually a youtube video) of the original song the chord chart is written out, which makes it easy to play along with the song at your preferred tempo. 
-Play along melody slices. With the audio (usually a youtube video) of the original song the melody is written out in notes and tabs. 
-Fingerstyle guitar arrangements. I arrange requested (pop)songs for guitar. 
-Riffs of pop and rock songs. 
-Written out guitar solos. 

Usually I am able to make a requested slice during the lesson. If there is no time for that or more time is required to finish the slice, I charge €10 per slice.

I also currently have five private courses in soundslice. Most course feauture over 30 different slice. Currently there is A strumming course, Strumming course pt2, Fingerstyle course, Blues guitar course, Rock guitar course. These courses are exclusively for anyone who studies with me.
