Ambiguous chord annotations in the Jazz-Corpus

[andreamust]

In the Jazz-Corpus there are (non-roman) annotations which can very often be ambiguous.
The ambiguity is mainly due to the placement of the alterations (after the root of the chord and before the degrees of the chord).

This generates annotations such as: Ebb5,7, which can be interpreted either as:

• flat E chord with flat fifth and seventh
• double flat E with fifth and seventh,
• E with double flat fifth and seventh.

The first hypothesis seems to be the strongest one.

Also frequent are annotations of the type %7, which is currently being interpreted as dominant seventh, but there is no documentation to prove this.

To check if the conversions are correct, possibly with the help of a musicologist.
