Q: how to you call a sus13 chord that have no fourth in it (only 7th 9th and 13th) ?
A: i'll give you all the options and you can decide which one is best. if you are in rehearsal and you have your instrument, just say 'this' and play it. if you are writing on the staff, you can just write the notes. if you are using chord symbols, you can say 'G9,13,no3no5' or you can say 'Fmaj7no5, over G'.... as you can see both chord symbol options are kind of a nightmare so if you use that chord a lot, perhaps you might want to make up your own shorthand symbol for it, and share it with other people you are working with
