As one of those aforementioned couch spuds (and a sneaker fan), I have noted with interest that the humble sneaker has left vital clues in many an episode of CSI. but HOW to separate fact from fiction? What role does the sneaker play in the forensic sciences? Aficionados may understandably muse over the merits of the speckled or gum sole, but the folks in the crime lab are more interested in the print shoes leave behind. As it happens, shoe prints are incredibly important clues often left at crime scenes.

The number of shoe print patterns out there is huge. Shoe print indices and databases have been developed in various countries. Commercial company Foster and Freeman have a range of software tools to identify shoes, including SICAR and SoleMate. Forensic Science Services (FSS) is a UK Government owned company that released an online footwear coding and detection management system this year, entitled Footwear Intelligence Technology.

I contacted Laura Mackin at the FSS who informed me that they have records of more than 20,000 shoe prints of which approximately 90 per cent come from sneakers. I was intrigued as to how the database was compiled; were they getting shoes from the manufacturers? From shops? As it happens, all of the prints come from shoes given to the FSS by the 43 police forces around the UK, either from marks left at a crime scene or from sneakers confiscated from a suspect. Interestingly, the FSS don’t have any special agreements with manufacturers. This was a bit of a disappointment as I was hoping to learn that the most comprehensive sneaker collection in the UK was at the FSS.

The FSS also offer the fantastically named ‘Cinderella Service’, which helps identify personal information about suspects including the angle of their footfall and weight distribution. Facey wrote in the journal Pattern Recognition that ‘shape and extent of the the general wear apparent on a shoe sole contains information about the foot function and gait of the wearer.’ The use of US Army anthropometric databases has allowed models to predict height based on shoe size. English tabloid newspaper The Mirror reported this June, with perhaps a hint of schadenfreude at the shoe manufacturer’s expense, that sneakers are the most popular shoes used by criminals as evidenced by shoe prints, and listed the top ten shoes for English crims.

The list I received from the FSS was exactly the same; so there haven’t been any changes in the sneaker buying habits of the criminal world in the last few months. Whilst this list may provoke some tittering amongst tabloid readers or annoyance for the manufacturers PR companies, no mention is made of what the top ten sneakers sold are, and whether the two lists are significantly different; ie most bad boys may wear the top ten listed but perhaps so do the general population in England. It would be interesting to see how these lists vary between countries. The data is also for all crimes, rather than category of crime. The FSS doesn’t store this info, and I can imagine the manufacturers are at least grateful for that.

As with any forensic test, the shoe print is not a tool to be used without caution. A survey in the 1996 issue of Forensic Science International demonstrated ‘remarkable variations’ in conclusions of shoe print reports from different laboratories examining the same cases! Hopefully computer databases have reduced the error rate. Miss Mackin (FSS) informed me that ‘footwear is the second most common evidence type after DNA and is capable of definitively putting someone at a crime scene, particularly thanks to the unique wear marks that each pair will have’.

The Mirror’s article has a quote from someone at Nike who said (in response to their shoes being six of the top ten worn in British crimes): ‘We are Britain’s best-selling trainer manufacturer so we’re not surprised we feature. We’ve no further comment.’ Whilst this indeed is common sense as previously noted, perhaps they should consider another approach; embrace it. I see it now, The Prisoner Pack; all orange Air Max 90s, black and white striped Air Max 95s. And why not cash in on the whole ‘all over print’ phenomenon and do some hyperstrikes that have an all over arrow motif!

Sometimes the teacher learns more from the student than the student does from the teacher. Hopefully, not too often, but today I would like to share with you some great practicing ideas that have come from my piano students over the years:

1. A Colonel in Virginia that I taught for several years got up at 4AM every weekday morning and practiced on an electronic keyboard with headphones so he wouldn't disturb anyone at that time of the morning. "I love the early morning", he said, "because it's so quiet and peaceful and I'm fresh and raring to go. No phones are ringing, no people walking into the room, no disturbances at all. I practice for a half-hour, have breakfast, and then hit it for another half-hour -- all before I have to show up for work. When I get home in the evening, if I'm too tired to practice, I don't feel guilty because I've already got my licks in for the day. And if I'm up to practicing some more -- well, it's a bonus!"

2. An elementary school teacher in Indiana told me she took each piece I assigned her and transposed it into all 12 keys -- not written out, but at the piano -- in her head. She said "It doesn't always sound so hot, but I find that if I keep at it day after day, I can at least get by in the most difficult keys, and it makes the easier keys seem real simple. And it gives me a perspective that I just wouldn't get it I just played it in one key -- the key it is written in. I've learned that each key has it's own "feel", and some keys are bright (like "D") and some keys are mellow (like "Db").

3. Another piano student with a similar idea, who was the Minister of Music in a Catholic church, said he took one whole month of the year and devoted it to mastering just one key. Since there are 12 months in the year and 12 Major keys, that works out perfectly. So in January he played everything he could find in the key of C, and transposed anything that wasn't in C into C. In February he went up 1/2 step to the key of C# (also known as Db enharmonically) and played everything in Db and searched for pieces written in the key of Db, and so on. By the time the year was up, he had a pretty fair grasp on the 12 Major keys. I suggested that he devote the next year to the 12 minor keys, and the next year to the modes, and the next year to polytonality, etc., etc. -- but as I recall he decided to just recycle through the 12 major keys, since he used them so much more than the ones I suggested.

4. Still another piano student took an idea from me and twisted it a bit. I suggested that she play along with pieces she liked on tapes and CD's, so she would get a feel for the motion of the song. (I used to do that by the hour when I was a teen-ager, and it paid off big time for me!). She took the idea and tried it and liked it so much that she started getting videos of people playing the piano. She arranged her TV and video player so that she could be at her piano while the video was playing, and she would play along with the pianist on the screen, following her/his hand motions and arm motions and finger position and thereby getting a feeling for the flow of the music. (Patterning). Her creativity is paying off for her -- she is advancing rapidly. (And by the way, don't think she is "copying" the person she is watching -- not at all. It's the same principle as watching Michael Jordan moving toward the basket, or watching Sammy Sosa swing a bat -- it just gets you in the right groove before you apply your own style to it.)

5. A doctor I have taught for years makes a idea file of things he has learned about piano playing over the years. He notes where in a given book or tape or video I discuss such and such a topic, and files that alphabetically. Then later when he needs to refer to that idea, he simply looks up the idea in his file, locates the video or cassette or book, and presto -- he can review that idea or concept almost instantly. It's like a card catalog in the library -- makes finding things so much faster than flipping through endless books trying to find that idea you saw long ago.
With the advent of the computer a person could store and categorize ideas such as this very quickly.

Hope this gives you some ideas of your own!
