To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The book I received looks like it has been printed and guillotined by a distracted primary school teacher. The print is not centred and just about remains on the page without sentences/music being sliced. Cheap looking, which is a shame.
I searched for 7 string Lyre handbook, this book is for a 6 string...however it does give a few good lessons, just make sure that you tune your 7 string the way you want (and ignore this 6 string setup).
